Nano World: Nanoparticle Toxicity Tests
Charles Q. Choi: Scientists have for the first time compared how toxic several different kinds of nanoparticles are with known toxic and nontoxic items and found certain nanoparticles appeared surprisingly toxic, experts told UPI's Nano World.
At the scale of nanometers or billionths of a meter, substances can take on radically different properties not seen in their bulk counterparts. As nanotechnology takes advantage these novel traits for use in a wide and growing range of applications, concerns are growing as to whether nanoparticles, nanotubes and other nanoscale components might have unintended consequences when exposed to humans or the environment.
Researcher Wendelin Stark, a chemical engineer at the Swiss Federal Institute of Technology in Zurich examined seven nanoparticles that are finding growing use by industry.
