EHP-in-Press Article Evaluates Silver Nanoparticle Toxicity

Lynn L. Bergeson

On October 23, 2009, EHP-in-Press posted an article entitled “Evaluation of Silver Nanoparticle Toxicity in vivo Skin and in vitro Keratinocytes,” which assesses the potential cytotoxicity of silver nanoparticles in human epidermal keratinocytes, and their inflammatory and penetrating potential into porcine skin in vivo. According to the article, silver nanoparticles are non-toxic when dosed in washed silver nanoparticle solutions or carbon-coated. The authors conclude that their study “provides a better understanding [of silver nanoparticles] safety in vitro as well as in vivo and a basis for occupational and risk assessment.” EHP-in-Press articles have been peer reviewed and accepted for publication in Environmental Health Perspectives.
