Nanotech in products sold today

After more than twenty years of basic and applied research, nanotechnologies are gaining in commercial use. Nanoscale materials now are in electronic, cosmetics, automotive and medical products. But it has been difficult to find out how many "nano" consumer products are on the market and which merchandise could be called "nano."

While not comprehensive, this inventory gives the public the best available look at the 200+ nanotechnology-based consumer products currently on the market. Prior to this inventory, the figure most often cited by the U.S. government was that approximately 80 consumer products containing nanomaterials were being sold.
