UA-Based Study Finds No Threat from Brief Exposure to Industrial Nanoparticles

A multi-university research team led by professor Reyes Sierra has found that nano-engineered materials widely used in semiconductor manufacturing pose low environmental risk. Their article, "Physical, chemical and in vitro toxicological characterization of nanoparticles in chemical mechanical planarization suspensions used in the semiconductor industry: towards environmental health and safety assessments," was one of the most downloaded papers for the journal Environmental Science Nano in 2015.
