The Dangers of Nanotech

In September Wired UK published my feature on the health risks of nanotechnology. The article is now online.

Nanotechnology's commercial growth has been accompanied by fears that it could damage human health and the environment. This in turn is stoking pressure on government and regulators to limit -- even ban -- a technology whose promise includes cleaner fuels, improved water filtration, better medicines, faster electronics and healthier foods.

Nice article. I am working in nanotechnology, and we find many curiously active (catalytic) compounds even with employing usual microwave ovens - rather suspicious in terms of health impact - nobody knows details. Not sure whether this implies stuff to be harmless or whether we should be more careful with heating cold pizza slices in the microwave, too.
I plan to post something on these issues next week.
