Using Nanotechnology

Nanoparticles are currently used in a number of different consumer products. Recently clay nanoparticles have been used in composite materials for cars and packaging materials, where they offer transparency and increased strength. Sunscreens utilize nanoparticulate zinc oxide, and new anti-aging skin creams are being developed with nanoparticles. Nanoparticles are also being used in antiseptics, as abrasives, in paints, in new coatings for spectacles (making them scratchproof and unbreakable), for tiles, and in electrochromic or self-cleaning coatings for windows. Nanoparticles are the basis for new anti-graffiti coatings for walls and improved ski waxes and ceramic coatings for solar cells. Glues containing nanoparticles have optical properties that give rise to uses in optoelectronics. Casings containing nanoparticles are being developed that shield against electromagnetic interference.
