The Appliance and Kitchen Gadgets blog strives to be about
more than just what new tools you can buy. We were struck by Steve Boggan's
recent article for the Guardian, which reminds us that new food technology can
affect us, even if we don't want it to.
A new word popping up all over the place is nanotechnology.
There is nanotechnology research into all sorts of things, including
pharmaceuticals, manufacturing, military intelligence and weaponry, and now,
even food. But as Boggan explains in his article, this is a revolution that has
met simultaneously with generous praise and severe criticism.
This is not surprising, considering the potential fruits of
this technology: scientists are boasting that using nanotech in foods could
completely change the way we think about food. Using nanotechnology, foods like
burgers and ice cream could be changed on the atomic level to taste just as
good without the fat or the calories. Boggan's article also mentions how
nanotech might provide protection against allergic reactions. He writes,
"If you are allergic to peanuts, perhaps you'd like to fix your food so
that any nut traces pass harmlessly through your body."

The Health Protection Agency has set up a new centre to
study the possible health effects of human exposure to nanoparticles. The
National Nanotoxicology Research Centre (NNRC) is being developed at the
Agency's Centre for Radiation, Chemical and Environmental Hazards (CRCE) at
Chilton in Oxfordshire. The Agency is collaborating with universities and the
Medical Research Council's (MRC) Toxicology Unit to develop the centre and its
research programme.
The Agency's Chairman Sir William Stewart said: "The
application of nanotechnology is an exciting development with many potential
benefits. However, it is very new technology and some element of precaution is
required. More research should be carried out into any possible health effects
from the use of nanoparticles, and that is the primary task of the new
centre."
The Agency will be collaborating with the Universities of
Birmingham, Cardiff, Edinburgh,
Imperial College
and King's College London and the MRC Toxicology Unit in Leicester.

Though you cannot see them, you may be touching them or even
wearing them right now. Products made using nanoparticles are already part of
our lives.
But the growth of this new industry has some scientists
worried that the minuscule particles may be carrying health and safety risks,
particularly since many come from toxic materials.
…Tran said the level of toxicity "is pretty much
unknown because of the lack of funding from the government and the lack of
funding from the industry. I wish the government provided more funding for the
universities and the industry to study thoroughly the side effects of
nanomaterials," he said.

Former EPA Official Highlights Shortcomings of Current
Federal Oversight
Nanotechnology will significantly change virtually every
facet of the way we live. The next president has the opportunity to shape these
changes and to ensure that nanotechnology's benefits will be maximized and its
risks identified and controlled. A new report by former EPA official J.
Clarence (Terry) Davies lays out a clear roadmap for the next presidential
administration and describes the immediate and longer term steps necessary to
deal with the current shortcomings of nanotechnology oversight.
"The future of the technology is in the hands of the
incoming administration. The shape of the future will depend significantly on
what the new government does," says Davies, whose report, Nanotechnology
Oversight: An Agenda for the New Administration, was released today.

New report forecasts major growth spurt in next seven years
July 22, 2008 -- The market for nanotechnology-based
products is expected to reach $3.1 trillion by 2015, up from $147 billion in
2007, according to a recent report by technology advisory firm Lux Research.
The forecast is based on data from more than 1,000 primary interviews Lux
Research analysts conduct with technology developers annually, as well as a new
survey of 31 top corporations active in nanotechnology.
Through 2015 the materials and manufacturing sector will
remain the top field for nanotechnology applications, growing at 45% to reach
$1.8 trillion worth of product revenue. The electronics sector will gain ground
through 2015, growing at a 51% compound annual growth rate to reach $940
billion, while healthcare and life sciences will grow at 46% annually to reach
$31 billion.
The United
States leads the way with $59 billion worth
of nanotech-based products produced in 2007. Europe
followed at $47 billion; Asia/Pacific accounts for $31 billion, and the rest of
the world accounted for $9.4 billion. However, Europe is expected to edge the United States in nanotech revenue with $1.09
trillion worth of products generated by 2015, compared with $1.08 trillion in
the U.S.
over the same period. Asia will remain in
third place at $717 billion.

As the presidential election season heats up, public policy
advocates and business groups are calling for greater oversight and more
funding for the budding nanotechnology industry.
A report due Wednesday from the nonpartisan Woodrow Wilson
International Center for Scholars contends that the White House should direct
federal agencies to apply existing laws more effectively and strengthen
nanotech oversight.
…He says clearer oversight would not only help to protect
health and the environment, but also drive more nanotech investment.
"Right now, there's no special legislation or
regulatory program dealing with nanotech," Davies said in an interview.
"That's something we've got to pay attention to."

A stable, reliable regulatory framework is essential to
advancing the R&D of nanotechnologies, European Commission (EC) vice
president Gunter Verheugen said as the commission initiated a public dialogue
on nanotech safety and the best way to apply existing laws to nanotech products
entering the market.
While existing EU legislation provides a starting point for
addressing public health and environmental concerns about nanotechnologies, the
commission cites a need for more research and international cooperation in the
field. With the proper regulatory structures in place, nanotechnologies could
"usher in a new age of customized pharmaceuticals and medical
procedures," the commission says in a statement.
The consultation is intended to raise awareness about the
potential benefits of nanotechnologies while ensuring the public and
environment are protected from adverse effects that may arise from exposure to
nanotech products.

The potential environmental risks of nanomaterials,
including their impact on aquatic organisms, have been a central argument for
regulating the nanotechnology sector. New research suggests that engineered
nanomaterials can be transferred from single celled organisms in the lowest
levels of the food chain, to higher, multi-celled organisms.
…These findings may be relevant to various policy sectors
concerned with the emerging area of nanotechnology, water pollution and
ecosystem health. The authors said that while their results suggest that
quantum dots may not pose a significant risk of accumulating in aquatic
invertebrate food chains, additional research beyond simple laboratory
experiments and a more exact means of quantifying transferred nanoparticles in
environmental systems are needed to be sure. Another factor in the natural
environment will be how other organic particles interact with the
nanoparticles.

A new technology will only be successful if those promoting
it can show that it is safe, but history is littered with examples of promising
technologies that never fulfilled their true potential and/or caused untold
damage because early warnings about safety problems were ignored. The
nanotechnology community stands to benefit by learning lessons from this
history.
…So as new nanomaterials move from the lab to the
marketplace, have we learnt the lessons of past technologies, or are we
destined to repeat the mistakes made with previous technologies? In 2001 an
expert panel commissioned by the European Environment Agency (EEA) published a
report, Late Lessons from Early Warnings: The Precautionary Principle 1896–2000,
which explored 14 case studies, all of which demonstrated how not heeding early
warnings had led to a failure to protect human health and the environment.

Consumers accept nanotechnology in nutrition for packaging
and, to a lesser extent, even the food itself. This is according to a study
from ETH Zurich’s
Institute for Environmental Decisions (IED).
Michael Siegrist, Professor at the Institute for
Environmental Decisions at ETH Zurich,
set about probing this issue. In a representative study, he and his research
team asked 337 randomly selected people from all over Switzerland
about their risk perception for various kinds of food and packaging that
benefit from the functions of the nanoparticles. “In the meantime, research and
industry know a whole range of potential nanotech uses for food. However, still
only very little is known about the risks of the technology and how the
consumers perceive them”, explains Siegrist. By publishing the results of the
study in the journal “Appetite”, however, he has bridged a gap in the knowledge
of how well nanotechnology is accepted in the food sector.

Any drug intended for systemic administration and all
medical devices which will contact blood (e.g. oxygenators, tubing, catheters,
artificial hearts) must undergo thorough biocompatibility testing. These tests
include an in vitro assay to determine the material's potential to damage red
blood cells (hemolysis). Hemolysis, the abnormal breakdown of red blood cells
either in the blood vessels (intravascular hemolysis) or elsewhere in the body
(extravascular), can lead to anemia or other pathological conditions. In the
pharmaceutical industry, hematocompatibility testing is harmonized through the
use of internationally recognized standard protocols. ASTM F756 – Standard
Practice for Assessment of Hemolytic Properties of Materials – is a widely used
standard for blood-damage testing. Another standard, ISO 10993-4, recommends
investigating red blood cell (erythrocyte) damage as a way to study a
material's compatibility with blood.
Nanotechnology-based medical devices and drug carriers are
emerging as alternatives to conventional small-molecule drugs, and in vitro
evaluation of their biocompatibility with blood components is a necessary part
of early preclinical development. Many research papers have reported
nanoparticle hemolytic properties but, so far, no in vitro hemolysis protocol
has been available that is specific to nanoparticles.
A new study published this month describes in vitro assays
to study nanoparticle hemolytic properties, identifies nanoparticle
interferences with these in vitro tests and provides the first comprehensive
insight to potential sources of this interference, demonstrates the usefulness
of including nanoparticle-only controls, and illustrates the importance of
physicochemical characterization of nanoparticle formulations and visually
monitoring test samples to avoid false-positive or false-negative results.

A North
Carolina State University study on public attitudes
towards nanotechnology, artificial intelligence and other emerging technologies
has cited that educating people about the new technologies results in those
people becoming more worried and cautious about the potential impact of the
same.
In the study, researchers, Dr. Michael D. Cobb, assistant
professor of political science, and Dr. Patrick Hamlett, associate professor of
science, technology and society and political science, gave questionnaires to
participants to determine their position on emerging technologies with human
enhancement applications - such as using nanotechnology to improve therapies
for injuries and degenerative diseases.
…The participants were then put through a deliberative
forum in March 2008 that provided structured discussions and educational
background on the technologies. Later they were asked to fill out the same
questionnaire they had been given before the deliberative forum and asked to
provide policy recommendations on how to handle the emerging science.

Forget about lead-tainted mascara or mercury in the salmon
filet. The new form of product pollution people are worrying about is
nanotechnology—the use of materials measured in billionths of a meter—and how
coming into contact with it might damage your health. Fueling the
nano-scare is negative press, including a report by the Environmental Working
Group that concluded hundreds of consumer products contain poorly-studied
nanoscale materials and a landmark study published in the journal Nature
Nanotechnology that suggests some forms of carbon nanotubes could be as harmful
as asbestos, which causes lung cancer if inhaled in sufficient quantities.
Though the Nature study points out risks in the fledging
nanotech industry, co-author Andrew Maynard says results like the one in his
study are good news, if only because they show that carbon nanotubes can be
made safe through more research and better regulations. “There’s already a
debate occurring about the potential safety issues of nanotech and how to get
around them,” says Maynard. "That's a good thing because it's something
that hasn't always happened with previous technologies.”
