One of the unique features of nanoscale materials is that they are often of the same size as most biomolecules, and thus can be used to study intracellular biochemistry without themselves having much of an impact on normal cellular function. Now, an international team led by investigators at McGill University has taken advantage of the small size of quantum dots to create a nanoscale device that can report on the oxidative conditions within a cell.
