The Dangers of Nanotech

In the growing field of nanotechnology, engineers are creating countless new microscopic materials. They're used in thousands of consumer goods, from cell phones to cosmetics and sunscreen. But how safe are they? To find out, we talked to Andrew Maynard, physicist and director of the Risk Science Center at the University of Michigan. We talked to him about the potential dangers of nanotech. Produced by David Levin. NOVA is produced by WGBH in Boston. Funding for NOVA is provided by David H.
