Information on Nanotechnology and Synthetic Biology
Nanotechnology is an experimental process that manipulates matter at the "nanoscale" (down to 1/100,000 the width of human hair) to create new products and materials. The nanoparticles in these products are so small, they can leach through our skin and cell and tissue membranes and spread through the environment in unpredictable ways.
Synthetic Biology is the design and construction of new biological parts, devices and systems that do not exist in the natural world and the redesign of existing biological systems to perform specific tasks.

A breed of Frankenfood is being introduced into human diet and cosmetics with potentially disastrous consequences, experts said last night. Academics, consumer groups and Government officials are warning that the arrival of nanotechnology threatens dangerous changes to the body and the environment.
The particles it uses are so small - 80,000 times thinner than a human hair - that they can pass through membranes protecting the brain or babies in the womb.

...Until recently ... even the most sophisticated laboratories could make only small snippets of DNA -- an extra gene or two to be inserted into corn plants, for example, to help the plants ward off insects or tolerate drought. Now researchers are poised to cross a dramatic barrier: the creation of life forms driven by completely artificial DNA. Scientists in Maryland have already built the world's first entirely [artificial] chromosome -- a large looping strand of DNA made from scratch in a laboratory. In the coming year, they hope to transplant it into a cell, where it is expected to [be Read more

The majority of consumers do not think that nanotechnology should be used in food applications, according to a survey from German risk assessor BfR, and they are more likely to trust information from consumer groups than politicians and businesses.
Nanotechnology refers to the control of matter at an atomic or molecular scale of between one and 100 nanometres (nm) - that's one millionth of a millimetre.
Despite still being in its infancy, current estimates on the value of products using nanotechnology put it currently in the range of US Read more

Louise A. Bunting has tiny reservations about selling sunscreen and makeup to customers at her Georgetown-area hair and tanning salon.
"Nano-size" reservations.
Bunting is on the front line in the emerging debate over the promise and pitfalls of nanotechnology -- the explosively growing business of making and using things smaller than 100 nanometers. A nanometer is one-billionth of a meter, and it takes 80,000 of them to equal the width of a human hair.
Nanoscale materials behave in unusual ways, combining with other materials like nothing else. In that Read more

PARIS - In a surprising reversal of roles, nanotechnology scientists outrival the general public in seeing a cause for concern in some aspects of their work, according to a study published Sunday.
Nanotechnology -- the science of making things measured in units 10,000 times smaller than the width of a human hair -- holds spectacular promise in virtually every sector.
Hundreds of consumer products already contain nano materials, most of which are cosmetics, sunscreens and cleaning products with microscopic particles.
But this is the only first step in what Read more

Imagine a solar panel without the panel. Just a coating, thin as a layer of paint, that takes light and converts it to electricity. From there, you can picture roof shingles with solar cells built inside and window coatings that seem to suck power from the air. Consider solar-powered buildings stretching not just across sunny Southern California, but through China and India and Kenya as well, because even in those countries, going solar will be cheaper than burning coal. That's the promise of thin-film solar cells: solar power that's ubiquitous because it's cheap. The basic technology has Read more

As the nanotechnology industry thunders ahead, filling consumer products with nanomaterials, experts worry about the lack of adequate oversight and regulation.
Get ready for a nanolife. Wake up in a bed with cotton sheets made bug-free with silver nanoparticles, brush your teeth with toothpaste bristling with nanogold, step into pants made dirt- and moisture-resistant through nanofibers, and go out with nanosunscreen on your skin. These nanobased consumer products are already on the market around the world, and the list is growing.

Scientists warned Wednesday that innovation in the emerging field of nanotechnology is being threatened by uncertainty about its risks.
The concerns were aired at a U.S. House subcommittee hearing about a lack of progress by the federal government in developing a plan to research nanotechnology's environmental, health and safety risks.
Nanotechnology is the design and control of matter that is 100 nanometers across, or smaller. A piece of paper is about 100,000 nanometers thick. According to the Project on Emerging Nanotechnologies, an independent advocacy group, more Read more
