potential nanoscale risks

Scientific American:

Smaller than a virus and used in more than 200 consumer products, silver nanoparticles can kill and mutate fish embryos, new research shows.

Tiny particles of silver – potent anti-microbial agents that can kill bacteria on contact – are becoming increasingly popular in consumer goods, including washing machines, refrigerators, clothing and toys.

“I think we jumped the gun” by creating such large volumes of nanoparticles, said University of Utah researcher Darin Furgeson. “We should take more time and really look at these new nano-systems before we start to throw them into personal products and shoot them into these ecosystems.”
