Purdue University scientists have found that when nanosilver – a nanoparticle growing in popularity as a bactericidal agent – is suspended in solution, its toxicity increases tenfold, causing birth defects and death in aquatic species. When the nanosilver was allowed to settle, the solution became several times less toxic but still caused malformations. The study, […]

Size matters! Nanosilver risks unknown, say watchdog group
Widespread use of nanoscale silver in consumer products will challenge regulatory agencies to balance important potential benefits against the possibility of significant environmental risk, says a new report by industry watchdog The Project on Emerging Nanotechnologies (PEN). The issue of risk and nanoscale silver was highlighted after the EPA earlier this year imposed a landmark […]
