Wilson, the sporting goods manufacturer, has nanoengineered layers
of clay to double the playing life
of its Double Core tennis balls; L'Oréal
uses nanoscale particles and capsules in their cosmetic creams that allow replenishing ingredients to penetrate deep into the skin; and the Australian company Advanced Powder Technology has created Zinclear, a translucent zinc oxide sunblock composed
of nanoparticles as small as the tiniest
known viruses.
Nanoparticles may already be a part
of your life you just don't
know too much about - they are in underwear, socks, and other performance clothing - and another area that could have
used a bit
of the precautionary principle before consumer products were launched on markets.
