risk. Nanotechnologies are no different. Certain nano-fabrication techniques employ toxic chemicals, the production of carbon nanotubes results in dangerous byproducts, and the big question as to what degree certain engineered nanoparticles could be harmful to humans and the environment has not been answered yet. The potentially adverse health effects of fine and ultrafine particles have been studied for decades. However, at the core of the nanotoxicological debate is the fact that nanoparticles are not just a smaller version of certain particles, but they are very different from their everyday counterparts with regard to their physical properties and catalytic activities. Thus their adverse effects cannot simply be derived from the known toxicity of the macro-sized material. One useful contribution to moving the nanotoxicology discu

Biomedical engineers at have announced pre-clinical test results in the September issue of the International Journal of Nanomedicine demonstrating the feasibility of a smart particle insulin release system that detects spikes in glucose or blood sugar levels and releases insulin to counteract them.
Designed to mimic functions of the pancreas which produces the blood-sugar regulating hormone insulin, the smart particle system stabilized blood sugar levels in a

"The convergence of nanotechnology and environmentally sensitive 'green building' is here, it's happening now," said Dr. George Elvin, director of Green Technology Forum and author of its latest report, "Nanotechnology for Green Building."
"In one case," Elvin noted, "a company is saving $2.6 million in energy costs and reducing their CO2 emissions by 35 million pounds per year thanks to a single nanotech innovation."

Industrial Revolution."
But how many Americans know what nanotechnology is? Does the U.S. public feel that the potential benefits of nanotechnology will outweigh potential risks? Who do people trust to monitor the safety of new technologies? And will they use food storage containers and food products enhanced with nanotechnology?
These questions were part of a representative national telephone survey of adults conducted in August 2007. It repeats a similar poll carried out last year -- which found that only one in 10 Americans had heard a lot about nanotechnology.
Results from the poll -- as well as from two complementary focus group discussions conducted among adult men and women about nanotechnology and food -- will be released by the Project on Emerging Nanotechnologies on Tuesday, September 25th at 12:30 p.m. at a program and liv

nanomachines. One important challenge is to make a tiny generator capable of providing power to accomplish a particular task. Although biomolecular motors have been used to drive nanodevices, they are complex and restricted by physiological conditions. In contrast this new nanomachine is simple, can be constructed from a variety of elements and uses an environmentally friendly fuel.
Geoffrey Ozin and colleagues from the University of Toronto have made a nanorod about 500 times thinner than a human hair, comprising two different metals; in this case gold and nickel. Very thin layers of these metals are deposited on top of one another to give a pattern like a conventional barcode.
One of the metals, nickel, can catalyse the decomposition of hydrogen peroxide to produce oxygen gas, propelling the nanorod through the solution. Thus

Professor Nikhil Koratkar has developed a new method to use carbon nanotubes for both detecting and repairing tiny cracks in nearly any polymer structure.
...
In this image, carbon nanotubes are randomly dispersed in an epoxy resin, which can be molded into different structures. By infusing the polymer with electrically conductive carbon nanotubes and monitoring the electrical resistance at different points in the structure, he can pinpoint the location and length of even the tiniest stress-induced crack. Once a crack is located, Kotakar can then send a short electrical charge to the area in order to heat up the carbon nanotubes and in turn melt an embedded healing agent that will flow into and seal the crack. - Photo Credit: Nikhil Koratkar Adding even a small amount of carbon nanotubes can go a long way toward enhancing the strength, integrity, and safety of plastic materials widely used in engineering applications, according to a new study.

...
October 2nd, 2007 The California Department of Toxic Substances Control (DTSC) will address minimizing the environmental and human health risks associated with the manufacture and use of nanotechnology products. Nanotechnology is the ability to measure, see, manipulate and manufacture things usually between 1 and 100 nanometers. A nanometer is one billionth of a meter; a human hair is roughly 100,000 nanometers wide. More than 500 consumer products made of nanoscale materials, including some electronics, cosmetics, automotive, and medical products have been identified by the Project on Emerging Nanotechnologies. Last year, nanotechnology was incorporated into more than $50 billion in manufactured goods, according to the Project on Emerging Nanotechnologies. By 2014, Lux Research estimates this figure will grow to $2.6 trillion. Explorin
