Nanotechnology

'Microspheres' prove devastatingly effective in trapping and killing tiny threats like bacteria and spores.

The race to know how nanoparticles affect living things is on, even as the use of those particles is increasing exponentially.

A generally risk-averse population in the Western world has so far been surprisingly welcoming of nanotechnology, a new meta-study finds.

While some experts say mum's the word when it comes to nanoproducts' environmental safety, others believe that cannot be good for the future of the technology.

A growing chorus of observers believes that nanotechnology needs better oversight, especially as it works its way into household staples like cosmetics and sunscreen.
