Researchers form Arizona State University recommended better standards for products containing silver nanoparticles, since simple leeching experiments in distilled water had shown that some anti-odor socks allegedly impregnated with silver nanoparticles, rapidly released their silver-content, while others caused no release at all.

The researchers noted that their study was not nanotechnology-specific, they exclaimed that ‘the history of silver and silver regulation has been set for decades by the U. S. Environmental Protection Agency — we’re not trying to reexamine or reinvent that.’ They concluded that standardisation of silver-containing products might be the way forward and suggest that improved product labeling could help: clothing labels could become like the back of a food packaging, complete with a list of “ingredients” like nanosilver.
