Nanotech At-a-Glance

Novel new technologies use extremely small particles on the nanometer scale. But some of these particles, while safe in larger groupings, have serious health consquences, as shown by current research.

Nanotechnology

The term 'nanotechnology' describes materials, systems and processes that exist or operate at the extremely small scale of a few hundred nanometres or less. To put a nanometre in context: a strand of DNA is 2.5nm wide, a red blood cell is 7,000 nm and a human hair is 80,000 nm wide.
