Rick Weiss, who used to work at the Washington Post, has been doing some impressive work for Science Progress, a site run by the liberal think tank Center for American Progress.
He’s been reporting on a series of meetings the FDA has been holding, and along the way, pointing out the challenges in regulating or even defining nanotechnology. One major point is that nanotech in cosmetics or clothing faces less regulation than if it’s sold as a drug.
The folks I know who work with nanotech want to diagnose and treat cancer with it, so they’ll have to endure the acid test of a clinical trial. Notably, the “nanoshell” technology developed by Halas and West at Rice appears to be entering its first clinical trials.
