Researchers in Texas are reporting that quantum dots (QDs) - a product of the revolution in nanotechnology increasingly used in electronics, solar cells, and medical imaging devices - may be toxic to cells under acidic or alkaline conditions. Their study, the first to report on how different pH levels may affect the safety of QDs, appears in the 15 January issue of ACS' Environmental Science and Technology, a semi-monthly journal...
