Testing the silver bullet: toxicity analysis of silver nanoparticles

The growing popularity of silver nanoparticles is evidenced by several newly marketed products based on their use, including socks that inhibit the growth of odour-causing bacteria, and washing machines that are designed to disinfect clothes. Despite their clear anti-bacterial properties, however, questions remain as to the potential toxicity of silver nanoparticles for humans exposed to them on a regular basis.
