(C&EN) To understand the toxicity of nanoparticles, most scientists have focused on the materials’ metal cores. But now researchers have shown that the chemicals that decorate silver nanoparticle surfaces can change their toxicity. Known for their antibacterial properties, silver nanoparticles find use in medical devices, textiles, and other products. In 2010, Mitchel Doktycz of Oak Ridge National Laboratory and his colleagues reported that unlike other silver nanoparticles, those with fatty oleate coatings were not toxic to bacteria...1/12 |
