A number of chemical companies are supplying data to the Environmental Protection Agency so it can assess whether nanoscale materials used in their products may pose health risks. Scientific American reports that 13 companies, including BASF and General Electric, have provided data to the EPA, and another 17 are expected to do so. Some scientists worry that the tiny nanoparticles or carbon nanotubes could interact with human tissue, perhaps having an asbestos-like effect on the lungs.

New Test Could Determine Toxicity of Nanoparticles

June 27, 2008 7:08 PM | Permalink | Comments (0)

Materials engineered to be smaller than the wavelength of visible light are finding increasing applications in medicine, engineering, even consumer products like face cream, but no one quite knows what impact they might have on human health. Now researchers at the University of Michigan have come up with a way to test the effects of nanoparticles on human cells, according to the Wired Science blog. They also found that if they coated certain particles with a gel, they could make them less toxic.
