Making quantum dots less toxic broadens users' options
Candace Stuart: Today quantum dots shine in the life sciences, where researchers tack them onto molecules in cells and use their fluorescing properties to track their movement. The tags allow scientists to spy on cellular processes and better understand the inner workings of biological systems.
But quantum dot manufacturers have their sights on much larger and more lucrative markets: solar cells, electronics and even diagnostics. Manufacturers have recognized that in order to achieve their goals, though, they'll need a much different quantum dot than those used in research.
