Building on the idea of using DNA to link up nanoparticles scientists at the U.S. Department of Energy's Brookhaven National Laboratory have designed a molecular assembly line for predictable, high-precision nano-construction.
Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.
If all existing nanomaterials were to be tested for toxicity, it would cost U.S. industries between $249 million and $1.18 billion, but the testing could take as long as 53 years at current levels of investment, according to the first study to estimate the costs and time needed for nanotox testing.
Michael Lebby, president of OIDA, testified Tuesday at a Congressional hearing on China's Industrial Policy and Its Impact on U.S. Companies, Workers and the American Economy. Chaired by Commissioners Patrick A. Mulloy and Daniel M. Slane, Lebby offered OIDA's perspective on the panel discussing China's Nanotechnology and Optoelectronics Industries.
Contact with a wide range of chemicals and other hazardous substances at work is endangering the health of workers across Europe, and nanotechnology is one of the risks causing most concern to experts from 21 European countries.
After engaging in a three-year learning process, European Trade Unions and European environmental NGOs have formulated position statements calling upon industry and governments to pursue the responsible development of nanotechnologies and to operationalise comprehensive precautionary measures that can effectively prevent harm to the user and the environment.
A new technology which dramatically improves the sensitivity of Magnetic Resonance techniques including those used in hospital scanners and chemistry laboratories has been developed by scientists at the University of York.
