Artist Kate Nichols longed to paint with the iridescent colors of butterfly wings, but no such pigments existed. So she became the first artist-in-residence at Lawrence Berkeley National Laboratory to synthesize nanoparticles and incorporate them into her artwork.
When I was assigned to work on our QUEST story on nanotechnology, I braced myself for the complex terrain ahead. The focus is on the public policy implications of the surge in consumer goods containing nanoparticles. And just how big is the market for nano-manufactured goods?
At 10,000 times smaller than the width of a human hair, you can't see nanoparticles, but you can find them in everyday products like sunscreen and clothing. But environmental and health concerns are mounting about exposure to nanomaterials, sparking a growing debate about their possible regulation.
