The number of consumer products using nanotechnology has more than doubled, from 212 to 475, in the 14 months since the Project on Emerging Nanotechnologies launched the world's first online inventory of manufacturer-identified nanotech goods in March 2006, reports the Project on Emerging Nanotechnologies. Clothing and cosmetics top the inventory at 77 and 75 products, respectively.
A list of nanotechnology products that also includes bedding, jewelry, sporting goods, nutritional and personal care items is available free at www.nanotechproject.org/consumerproducts.
