Quantum Dot-Dopamine Study

In Washington, scientists at the Naval Research Laboratory (NRL), in conjunction with the Scripps Research Institute in La Jolla, Calif., have reported a detailed study of the interactions of water-soluble semiconductor quantum dots and the electroactive neurotransmitter dopamine. The biocompatible nanoassemblies could be used as active components in sensors that detect a variety of target analytes, including sugar and peroxide. The research was supported by NRL’s Nanoscience Institute and the Defense Threat Reduction Agency.
