Turning all the lights on: quantum dots in cellular assays

Quantum dot materials are increasingly used in cellular assays, and offer a powerful and enabling complement to existing methods of labeling proteins, such as green fluorescent protein. These materials give researchers the ability to study specificity and functional responses in cellular systems, in a highly multiplexed manner, at either a molecular or cellular level. The recent literature bears witness to the increasing use of quantum dots for the investigation of chemicals on biological systems, and paves the way to the use of these assays for high-throughput analysis of functional responses in relevant models at scales including molecular, cellular and whole animal.
