Nanobiotechnology

http://www.etcgroup.org/article.asp?newsid=373

 

If the word registers in the public consciousness at

all, " nanotechnology " conjures up visions of itty-bitty mechanical

robots building BMWs, burgers or brick walls. For a few, nanotech

inspires fear that invisible nanobots will go haywire and multiply

uncontrollably until they suffocate the planet – a scenario known

as " Gray Goo. " Still others, recalling Orwell's 1984, see nanotech

as the path to Big Brother's military-industrial dominance, a kind

of " gray governance. " Gray Goo or gray governance – both are

plausible outcomes of nanotechnology – the manipulation of matter at

the scale of the nanometer (one billionth of a meter) – but possibly

diversionary images of our techno-future.

 

The first and greatest impact of nano-scale technologies may come

with the merger of nanotech and biotech – a newly recognized

discipline called nanobiotechnology. While Gray Goo has grabbed the

headlines, self-replicating nanobots are not yet possible. The more

likely future scenario is that the merger of living and non-living

matter will result in hybrid organisms and products that end up

behaving in unpredictable and uncontrollable ways – get ready

for " Green Goo! "

 

Impact: Roughly one-fifth (21%) of nanotech businesses in the USA

are currently focusing on nanobiotechnology for the development of

pharmaceutical products, drug delivery systems and other healthcare-

related products.1. The US National Science Foundation predicts that

the market for nano-scale products will reach $1 trillion per annum

by 2015. As with biotech before it, nanotech is also expected to

have a major impact on food and agriculture.

 

Policies: No single intergovernmental body is charged with

monitoring and regulating nanotechnology. There are no

internationally accepted scientific standards governing laboratory

research or the introduction of nano-scale products or materials.

Some national governments (Germany and the USA, for example) are

beginning to consider some aspects of nanotechnology regulation but

no government is giving full consideration to the socioeconomic,

environmental and health implications of this new industrial

revolution.

 

Fora: Informed international debate and assessment is urgently

needed. Initiatives include: FAO's specialist committees should

discuss the implications of nanotechnology for food and agriculture

when they convene in Rome in March 2003. The Commission on

Sustainable Development should review the work of FAO and consider

additional initiatives during its New York session, April 28-May 9,

2003. The World Health Assembly, the governing body of the World

Health Organization, should address health implications of

nanotechnology when it meets in Geneva in May 2003. Ultimately,

governments must begin negotiations to develop a legally binding

International Convention for the Evaluation of New Technologies

(ICENT).

 

Introduction: Nanotech+Biotech

 

This year marks the 50th anniversary of the discovery of the double-

helix – the structure of the DNA molecule and the catalyst for the

biotechnology revolution. Also in the 1950s, physicist Richard

Feynman theorized that it would be possible to work " at the bottom " –

to manipulate atoms and molecules in a controlled and precise way.

Today, our capacity to manipulate matter is moving from genes to

atoms. Nanotechnology refers to the manipulation of atoms and

molecules to create new products. ETC Group prefers the

term " Atomtechnology, " not only because it is more descriptive, but

also because nanotechnology implies that the manipulation of matter

will stop at the level of atoms and molecules – measured in

nanometers. Atomtech refers to a spectrum of new technologies that

operate at the nano-scale and below – that is, the manipulation of

atoms, molecules and sub-atomic particles to create new products.

 

At the nano-scale, where objects are measured in billionths of

meters, the distinction between living and non-living blurs. DNA is

just another molecule, composed of atoms of carbon, hydrogen,

oxygen, nitrogen and phosphorous – chemical elements of the Periodic

Table – that are bonded in a particular way and can be artificially

synthesized.2. The raw materials for Atomtechnology are the chemical

elements of the Periodic Table, the building blocks of all matter.

Working at the nano-scale, scientists seek to control the elements

of the Periodic Table in the way that a painter controls a palette

of pigments. The goal is to create new materials and modify existing

ones.

 

Size can change everything. At the nano-scale, the behavior of

individual atoms is governed by quantum physics. Although the

chemical composition of materials remains unchanged, nano-scale

particles often exhibit very different and unexpected properties.

Fundamental manufacturing characteristics such as colour, strength,

electrical conductivity, melting point – the properties that we

usually consider constant for a given material – can all change at

the nano-scale.

 

Taking advantage of quantum physics, nanotech companies are

engineering novel materials that may have entirely new properties

never before identified in nature. Today, an estimated 140 companies

are producing nanoparticles in powders, sprays and coatings to

manufacture products such as scratchproof eyeglasses, crack-

resistant paints, transparent sunscreens, stain-repellant fabrics,

self-cleaning windows and more. The world market for nanoparticles

is projected to rise 13% per annum, exceeding US$900 million in

2005.3.

 

But designer nanoparticles are only the beginning. Some nano-

enthusiasts look eagerly to a future when " nanobots " (nano-scale

robots) become the world's workhorses. " Molecular nanotechnology "

or " molecular manufacture " refers to a future stage of

nanotechnology involving atom-by-atom construction to build macro-

scale products. The idea is that armies of invisible, self-

replicating nanobots (sometimes called assemblers and replicators)

could build everything – from hamburgers to bicycles to buildings. A

lively debate revolves around the extent to which molecular

manufacturing will be possible – but scientists are already taking

steps in that direction.4.

 

Gray Goo:

 

Gray Goo refers to the obliteration of life that could result from

the accidental and uncontrollable spread of self-replicating

nanobots. The term was coined by K. Eric Drexler in the mid-1980s.

Bill Joy, Chief Scientist at Sun MicroSystems, took Drexler's

apocalyptic vision of nanotechnology run amok to a wider public.5.

 

Drexler provides a vivid example of how quickly Gray Goo could

devastate the planet, beginning with one rogue replicator. " If the

first replicator could assemble a copy of itself in one thousand

seconds, the two replicators could then build two more in the next

thousand seconds, the four build another four, and the eight build

another eight. At the end of ten hours, there are not thirty-six new

replicators, but over 68 billion. In less than a day, they would

weigh a ton; in less than two days, they would outweigh the Earth;

in another four hours, they would exceed the mass of the Sun and all

the planets combined. " 6.

 

To avoid a Gray Goo apocalypse, Drexler and his Foresight Institute,

a non-profit organization whose purpose is to prepare society for

the era of molecular nanotechnology (MNT), have established

guidelines for developing " safe " MNT devices. Foresight recommends

that nano-devices be constructed in such a way that they are

dependent on " a single artificial fuel source or

artificial `vitamins' that doesn't exist in any natural

environment. " 7. Foresight also suggests that scientists

program " terminator " dates into their atomic creations…and update

their computer virus-protection software regularly?

 

Most nanotech industry representatives have dismissed the

possibility of self-replicating nanobots and pooh-pooh the Gray Goo

theory. The few who do talk about the need for regulation believe

that the benefits of nanotech outweigh the risks and call for

industry self-regulation.8.

 

The Gray Goo theory is plausible, but are mechanical, self-

replicating nanobots really the road the nanotech industry will

travel?

 

Buccolic Biotech: The biotech industry provides an important history

lesson. Back in the early days, biotech enthusiasts promised durable

disease resistance in plants, drought tolerance and self-fertilizing

crops. But when the agbiotech companies marketed their first

commercial genetically modified (GM) products in the mid 1990s,

farmers were sold herbicide-tolerant plant varieties – GM seeds able

to survive a toxic shower of corporate chemicals. The agrochemical

industry recognized that it is easier and cheaper to adapt plants to

chemicals than to adapt chemicals to plants. By contrast, the money

involved in getting a new chemical through the regulatory maze runs

into the hundreds of millions.

 

More recently, the biotech industry has figured out that GM crops

could be cheaper, more efficient " living factories " for producing

therapeutic proteins, vaccines and plastics than building costly

manufacturing facilities. Companies are already testing " pharma

crops " at hundreds of secret, experimental sites in the United

States. While pharma crops may be cheaper and more efficient,

industry is plagued by a persistent problem: living modified

organisms are difficult to contain or control. Most recently, Texas-

based biotech company ProdiGene was fined $250,000 in December 2002

when the US Department of Agriculture discovered that stalks of the

company's pharma corn, engineered to produce a pig vaccine, had

contaminated 500,000 bushels of soybeans.9.

 

Atom & Eve in the Garden of Green Goo?

 

Atom & Eve: The nanotech industry seems to be following the biotech

industry's strategy. Why construct self-replicating mechanical

robots (by any standards an extraordinarily difficult task) when

self-replicating materials are cheaply available all around? Why not

replace machines with life instead of the other way around? Nanotech

researchers are increasingly turning to the biomolecular world for

both inspiration and raw materials. Nature's machinery may

ultimately provide the avenue for atomic construction technology,

precisely because living organisms are already capable of self-

assembly and because they are ready-made, self-replicating machines.

This is nanobiotechnolgy – manipulations at the nano-scale that seek

to bring Atom (nano) & Eve (bio) together, to allow non-living

matter and living matter to become compatible and in some cases

interchangeable. But will the nanobiotech industry find itself

battling out-of-control bio-nanobots in the same way that the

biotech industry has come up against leaky genes? Will today's

genetic pollution become tomorrow's " Green Goo? "

 

" The question now is not whether it is possible to produce hybrid

living/nonliving devices but what is the best strategy for

accelerating its development. " – Carlo D. Montemagno 10.

 

Mergers and Acquisitions: When the living and non-living nano-realms

merge in nanobiotechnology, it will happen on a two-way street.

Biological material will be extracted and manipulated to perform

machine functions and to make possible hybrid

biological/nonbiological materials. Just as we used animal products

in our early machines (e.g., leather straps or sheep stomachs), we

will now adopt bits of viruses and bacteria into our nanomachines.

Conversely, non-biological material will be used within living

organisms to perform biological functions. Reconfiguring life to

work in the service of machines (or as machines) makes economic and

technological sense. " Life, " after all, " is cheap " and, at the level

of atoms and molecules, it doesn't look all that different from non-

life. At the nano-scale, writes Alexandra Stikeman in Technology

Review, " the distinction between biological and nonbiological

materials often blurs. " 11. The concepts of living and non-living are

equally difficult to differentiate in the nanoworld.

 

Researchers are hoping to blend the best of both worlds by

exploiting the material compatibility of atoms and molecules at the

nano-scale. They seek to combine the capabilities of nonbiological

material (such as electrical conductivity, for example) with the

capabilities of certain kinds of biological material (self-assembly,

self-repair and adaptability, for example).12. At the macro-scale,

researchers are already harnessing biological organisms for

miniaturized industrial functions. For example, researchers at Tokyo

University are remote-controlling cockroaches that have been

surgically implanted with microchips. The goal is to use the insects

for surveillance or to search for disaster victims. Recent examples

of nanobiotechnology include:

 

Hybrid Materials: Scientists are developing self-cleaning

plastics with built-in enzymes that are designed to attack dirt on

contact.13. In the same vein, researchers are considering the

prospect of an airplane wing fortified with carbon nanotubes stuffed

with proteins. (Nanotubes are molecules of pure carbon that are 100

times stronger than steel and six times lighter.) If the airplane

wing cracks (and the tubes along with it), the theory goes,

fractured nanotubes would release the proteins, which will act as an

adhesive – repairing the cracked wing and protracting its life span.

Other scientists, using DNA as " scaffolding " to assemble conductive

nonbiological materials for the development of ultrafast computer

circuitry, are pioneering a new field of bioelectronics.14.

 

Should we be thinking about the General Motors assembly line or the

interior of a cell of E. coli? – George M. Whitesides, Harvard

University chemist 15.

 

Proteins Working Overtime: Proteins, the smallest class of

biological machines, are proving to be flexible enough to

participate in all kinds of extracurricular activities. A team of

researchers at Rice University has been experimenting with F-actin,

a protein resembling a long, thin fiber, which provides a cell's

structural support and controls its shape and movement.16. Proteins

like F-actin allow the transportation of electricity along their

length. The researchers hope these proteins can one day be used as

biosensors – acting like electrically conductive nanowires. Protein

nanowires could replace silicon nanowires, which have been used as

biosensors but are more expensive to make and would seem to have a

greater environmental impact than protein nanowires.

Cell Power! A more complex working nanomachine with a biological

engine has already been built by Carlo Montemagno (now at the

University of California at Los Angeles). Montemagno's team

extracted a rotary motor protein from a bacterial cell and connected

it to a " nanopropeller " – a metallic cylinder 750 nm long and 150 nm

wide. The biomolecular motor was powered by the bacteria's adenosine

triphosphate (known as ATP – the source of chemical energy in cells)

and was able to rotate the nanopropeller at an average speed of

eight revolutions per second.17. In October 2002, the team of

researchers announced that by adding a chemical group to the protein

motor, they have been able to switch the nanomachine on and off at

will.18.

 

Molecular Carpentry: The motto of NanoFrames, a self-

classified " biotechnology " company based in Boston, is " Harnessing

nature to transform matter. " 19. That motto is also a concise

description of how Atom & Eve works. NanoFrames uses

protein " subunits " to serve as basic building blocks (derived from

the tail fibers of a common virus called Bacteriophage T4). These

subunits are joined to each other or to other materials by means of

self-assembly to produce larger structures. NanoFrames calls their

method of manufacture " biomimetic carpentry, " but that label, while

wonderfully figurative, comes up short. Using protein building

blocks to take advantage of their ability to self-assemble is more

than imitating the biological realm (mimesis is Greek and means

imitation). It's not just turning to biology for design inspiration –

it is transforming biology into an industrial labor force.

 

DNA Motors: Using a different kind of module – DNA – but similar

logic, scientists are creating other kinds of complex devices from

simple structures. In August 2000, researchers at Bell Labs (the R & D

branch of Lucent Technologies) announced that they, along with

scientists from the University of Oxford, had created the first DNA

motors.20. Taking advantage of the way pieces of DNA will lock

together in only one particular way and their ability to self-

assemble, researchers created a device resembling tweezers from two

DNA strands. The tweezers remain open until " fuel " is added, which

closes the tweezers. The fuel is simply another strand of DNA of a

different sequence that allows it to latch on to the device and

close it. Physicist Bernard Yurke of Bell Labs sees the DNA motor

leading to " a test-tube technology that assembles complex

structures, such as electronic circuits, through the orderly

addition of molecules. " 21.

 

Living Plastic: Materials science researchers around the world

are trying to perfect the manufacture of new kinds of plastics,

produced by biosynthesis instead of chemical synthesis: the new

materials are " grown " by bacteria rather than mixed in beakers by

chemists in labs. These materials have advantages over chemically

synthesized polymers because they are biocompatible and may be used

in medical applications. Further, they may lead to the development

of plastics from non-petrochemical sources, possibly revolutionizing

a major multinational industry.22. In one example, E. coli was

genetically engineered – three genes from two different bacteria

were introduced into the E. coli– so that it was able to produce an

enzyme that made possible the polymerization reaction. In other

words, a common bacteria, E. coli, was genetically manipulated so

that it could serve as a plastics factory.23.

 

Merging the living and non-living realms in the other direction –

that is, incorporating non-living matter into living organisms to

perform biological functions – is more familiar to us (e.g.,

pacemakers, artificial joints), but presents particular challenges

at the nano-scale. Because nanomaterials are, in most cases, foreign

to biology, they must be manipulated to make them biocompatible, to

make them behave properly in their new environment.

 

Olympic Nano: Researcher Robert Freitas is developing an

artificial red blood cell that is able to deliver 236 times more

oxygen to tissues than natural red blood cells.24. The artificial

cell, called a " respirocyte, " measures one micron (1000 nanometers)

in diameter and has a nanocomputer on board, which can be

reprogrammed remotely via external acoustic signals. Freitas

predicts his device will be used to treat anemia and lung disorders,

but may also enhance human performance in the physically demanding

arenas of sport and warfare. Freitas states that the effectiveness

of the artificial cells will critically depend on their " mechanical

reliability in the face of unusual environmental challenges " and on

their biocompatibility. Among the risks, considered rare but real,

Freitas lists overheating, explosion and " loss of physical

integrity. "

 

Remote Control DNA: Researchers at MIT, led by physicist Joseph

Jacobson and biomedical engineer Shuguang Zhang, have developed a

way to control the behavior of individual molecules in a crowd of

molecules.25. They affixed gold nanoparticles (1.4 nm in diameter)

to certain strands of DNA. When the gold-plated DNA is exposed to a

magnetic field, the strands break apart; when the magnetic field is

removed, the strands re-form immediately: the researchers have

effectively developed a switch that will allow them to turn genes on

and off. The goal is to speed up drug development, allowing

pharmaceutical researchers to simulate the effects of a drug that

also turns certain genes on or off. The MIT lab has recently

licensed the technology to a biotech startup, engeneOS, which

intends to " evolve detection and measurement in vitro into

monitoring and manipulation at the molecular scale in cells and in

vivo. " 26. In other words, they intend to move these biodevices out

of the test tube and into living bodies.

 

 

 

Nanobiotechnology: What are the Implications?

 

Green Goo: Human-made nanomachines that are powered by materials

taken from living cells are a reality today. It won't be long before

more and more of the cells' working parts are drafted into the

service of human-made nanomachines. As the merging of living-nano

and non-living nano becomes more common, the idea of self-

replicating nanomachines seems less and less like a " futurist's

daydream. " In his dismissal of the possibility of molecular

manufacture, Harvard University chemist George Whitesides states

that " it would be a staggering accomplishment to mimic the simplest

living cell. " 27. But we may not have to " reinvent the wheel " before

human-made molecular creations are possible; we can just borrow it.

Whitesides believes the most dangerous threat to the environment is

not Gray Goo, but " self-catalyzing reactions, " that is, chemical

reactions that speed up and take place on their own, without the

input of a chemist in a lab.28. It is here – where natural

nanomachines merge with mechanical nanomachines – that the Green Goo

theory resonates strongest. The biotech industry has been unable to

control or contain the unwanted escape of genetically modified

organisms. Will the nanotech industry be better able to control

atomically modified organisms? Nanobiotechnology will create both

living and non-living hybrids previously unknown on earth. Will a

newly-manufactured virus retrofitted with nano-hardware evolve and

become problematic? The environmental and health implications of

such new creations are unknown.

 

Six Degrees of Humanity: Can societies that have not yet come to

grips with the nature of being human soldier on to construct

partially-human, semi-human or super-human cyborgs?

 

Natural Born Killers: As the merging of living cells and human-made

nanomachines develops, so will the sophistication of biological and

chemical weaponry. These bio-mechanical hybrids will be more

invasive, harder to detect and virtually impossible to combat.

 

Gray Governance: A 1999 study by Ernst & Young predicted that by

2010, there will be 10,000 connected microsensors for every person

on the planet.29. Nanosensors will undoubtedly surpass these

numbers. What happens when super-smart machines and unlimited

surveillance capacity get in the hands of police or military or

governing elites? These technologies will pose a major threat to

democracy and dissent and fundamental human rights. The powerfully

invasive and literally invisible qualities of nano-scale sensors and

devices become, in the wrong hands, extremely powerful tools for

repression.

 

[text box] Wanted: A Molecular Recipe for Manufacturing Life

 

In November 2002, the outspoken gene scientist J. Craig Venter and

Nobel Laureate Hamilton Smith announced that they were recipients of

a $3 million grant from the US Energy Department to create a

new, " minimalist " life form in the laboratory – a single-celled,

partially human-made organism.30. The goal is to learn how few genes

are needed for the simplest bacterium to survive and reproduce. " We

are wondering if we can come up with a molecular definition of

life, " Venter told the Washington Post. 31.

 

The researchers will begin with Mycoplasma genitalium, a simple

microbe that lives in the genital tracts of people. After removing

all genetic material from the organism, the researchers will

synthesize an artificial chromosome and insert it into the " empty "

cell. The longer-term goal is to manufacture a designer bacterium

that will perform human-directed functions, such as a microbe that

can absorb and store carbon dioxide from power plant emissions.

 

In essence, the mixing and matching of basic chemicals –

synthesizing DNA to create a brand-new life form – is a grand

experiment in nanobiotechnology. Will it also bring us Green Goo?

 

There are concerns that a partially human-made organism will provide

the scientific groundwork for a new generation of biological

weapons. Ironically, Venter abandoned his earlier quest to construct

the world's first simple artificial life form in 1999 because he

believed that the risk of creating a template for new biological

weaponry was too great.32. This time, Venter asserts, " We may not

disclose all the details that would teach somebody else how to do

this. " 33.

 

Toward a Double-Green Goo Revolution?

 

Not for the first time, some scientists are predicting a " double-

green " revolution. This time they say that nanotech will both

improve the environment and contribute to human well-being –

especially in the sectors of food and pharmaceuticals. (Civil

society organizations with a history in biotech will experience an

immediate déjà vu when they hear these claims.)

 

Slow Food Movement: Merging nanotech with biotech has enormous

implications for food, agriculture and medicine. Some scientists

dream of a world in which nanotech will allow our foods to assemble

themselves from basic elements to become the entrée of the day.34.

No need to waste time planting and harvesting crops or fattening up

livestock. No need for land – or farmers – at all. Just slip a

polymer plate in the nanowave and out pops the family feast. It is,

of course, theoretically possible to build a Big Mac or a Mac Apple

or even the Big Apple atom-by-atom. But, at the current rate of

construction, dinner would be late. In fact, nano food construction

would bring a whole new dimension to the Slow Food Movement. Dinner

won't be ready until sometime after hell freezes over!

 

But if nanobiotechnology can't mash the potatoes just yet, there is

still a great deal that these two converging technologies can

accomplish within the life sciences…

 

Green Goo Giants: Although not always defined as nanotechnology, the

Gene Giants and multinational food processors are either tracking

nanotech or are actively engaged in developing the technologies. In

a fall 2000 interview, Monsanto's then-CEO, Robert Shapiro,

commented on the most promising emerging technologies, " …there are

three, although I have a feeling that, under some future unified

theory, they will turn out to be just one. The first is, of course,

information technology… The second is biotechnology… And the third

is nanotechnology. " 35.

 

Jozef Kokini, Director of Rutgers' Center for Advanced Food

Technology, summarizes agribusiness's interest in nano-scale

technologies, " In our opinion, this is one technology that will have

profound implications for the food industry, even though they're not

very clear to a lot of people. " 36.

 

 

 

Special " K " : Kraft Foods may be more clear-sighted. In 1999, the $34

billion Philip-Morris subsidiary established the industry's first

nanotechnology food laboratory. In 2000, Kraft launched the NanoteK

consortium, enveloping fifteen universities and public research

labs, bent on basic research in food technology.37. NanoteK is a

heady broth of molecular chemists, engineers and physicists.

Consortium participants include Harvard, Connecticut, and Nebraska

universities, Chicago-based Argonne laboratories and the Los Alamos

Lab famed for their role in developing America's nuclear capacity.

But NanoteK is not a US preserve. Much of the intellectual might

comes from the Spanish universities of Seville and Málaga and from

Uppsala University in Sweden. The venture may already be bearing

fruit.

 

Smart Drinks: Kraft's first nano consumable may be a nano-capsule

beverage.38. Nanoparticles will encapsulate specific flavors,

colours or nutritional elements that can be activated by zapping the

solution with the appropriate radio frequency. Grocery stores and

vending machines would sell a colourless, tasteless bottled fluid

that customers could take home, zap, and transform into their

beverage of choice. Microwave frequencies would activate the

selected nano-capsules, effectively turning water into wine – or

coffee – or single-malt scotch. Since the same mechanism could be

used to release highly-concentrated drugs, the same bottled fluid

might offer the Alka-Seltzer chasers for the scotch. Smart hangovers!

 

Smart Foods: Another innovation showing commercial potential is the

addition of colour changing agents on food (or packaging), to alert

the processor or the consumer to unsafe food.39. Using " electronic

tongue " technology, sensors that can detect chemicals at parts per

trillion, the industry hopes to develop meat packaging that would

change colour in the presence of harmful pathogens.40. Food

poisoning is already a major health risk and product recalls cause

giant headaches for industry. Given the heightened concerns over

bioterrorism, this is a nano-product with enormous commercial

potential.

 

Out-of-Sight, Out-of-Mind?

 

Ready or not, nanotech is on its way. While much of the world has

been mesmerized by G3 mobile phones and GM foods, the nanotech

revolution is evolving quietly beneath the radar screen of

government regulators and below the trip wires of life itself.

 

Because nano-scale technologies can be applied to virtually every

industrial sector, no regulatory body is taking the lead. And

because many of its products are nano-sized versions of conventional

compounds, regulatory scrutiny has been deemed unnecessary. So far,

nano-scale technologies are out-of-sight and out-of-mind for most

politicians, regulators and the public.

 

The hard questions have not been asked. Basic questions like what

mischief can nanoparticles create floating around in our ecosystem,

our food supply and in our bodies? What happens when human-made

nanoparticles are small enough to slip past our immune systems and

enter living cells? What might be the socioeconomic impacts of this

new industrial revolution? Who will control it? Shouldn't

governments apply the Precautionary Principle? What if self-

replicating nanobots – whether mechanical or biological or hybrids –

multiply uncontrollably?

 

The world's most powerful emerging technology, Atomtechnology is

developing in an almost-total political and regulatory vacuum. Even

following ETC Group's July report warning that new nano-scale

particles could pose a significant environmental and health issue –

and advising further that no regulatory mechanisms exist covering

nanotech research, neither governments nor industry have moved

seriously to address these issues.41. Meetings held by the U.S.

Environmental Protection Agency with the U.S. National Science

Foundation this past August have not led to calls for broad public

discourse or regulation. Such failures threaten democracy and fuel

fears of environmental harm and gray governance control over nano-

scale technologies. Civil society organizations are beginning to

embrace nano-scale technologies as an issue that must be addressed.

 

At the international level, ETC Group believes that

intergovernmental bodies should begin an evaluation of the societal

impacts of nano-scale technologies immediately. Eight specific

initiatives should lead to an informed international debate at the

UN General Assembly.

 

Researchers should immediately volunteer – or governments should

impose – a moratorium on new nanoparticle laboratory research until

agreement can be reached, within the scientific community, on

appropriate safety protocols for this research. Draft protocols

should be available for public and governmental consideration as

soon as possible;

The agricultural and food implications of Atomtechnology and

nanobiotechnology should be discussed by the FAO committee on

agriculture at its next meeting in March, 2003 in Rome;

The health considerations related to Atomtechnology and

nanobiotechnology should be discussed by the WHO's World Health

Assembly when it convenes in Geneva in May, 2003;

The Commission of the European Union should bring forth a

directive to properly address the social and environmental risks of

nanotechnology, based on the precautionary principle;

The International Labor Organization (ILO) should evaluate the

socioeconomic impact of new nanotechnologies during the next meeting

of its governing body;

The technology division of the United Nations' Conference on

Trade and Development (UNCTAD) should undertake an immediate

evaluation of the trade and development implications/opportunities

of Atomtechnology for developing countries;

At its upcoming session in New York beginning the end of April,

the UN Commission on Sustainable Development (CSD) should address

the societal implications of nano-scale technologies;

Based on the recommendations of the specialized agencies of the

United Nations and the CSD, the UN General Assembly should launch

the process of developing a legally binding International Convention

on the Evaluation of New Technologies (ICENT).

responsible, professional culture. " For more information, see:

http://www.pacificresearch.org/press/rel/2002/pr_02-11-20.html The

Center for Responsible Nanotechnology, (CRN), also an avid proponent

of nanotechnology, is a new organization that conducts research and

education about molecular nanotechnology. CRN believes that

advanced, self-replicating nanotechnology is so powerful and

dangerous that it could " raise the specter of catastrophic misuse

including gray goo. " But CRN believes molecular nanotechnology is

inevitable and can be used safely. According to CRN, " Well-informed

policy must be set, and administrative institutions carefully

designed and established, before molecular manufacturing is

developed. " CRN was co-founded by Chris Phoenix, a senior associate

at the Foresight Institute, and Mark Treder, Treasurer of the World

Transhumanism Association. The website of the Center for Responsible

Nanotechnology is: http://responsiblenanotechnology.org/links.htm
