Nanotoxicology study shows good results

OAK RIDGE, Tenn. -- U.S. scientists at the Oak Ridge National Laboratory and the University of Tennessee report good results from a new nanotoxicology study.

The researchers, led by Meng-Dawn Cheng, studied single-walled carbon nanohorns -- a particular form of engineered carbon-based nanoparticles -- for drug delivery and other commercial applications.

The scientists reported no pulmonary toxicity issues for single-walled carbon nanohorns, contrary to numerous studies in rats involving single-walled carbon nanotubes that have different shapes and sizes than those of nanohorns.
