Quantum Dot-Dopamine Study

Photonics Spectra
Dec 2010
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.

GLOSSARY
quantum dots
Also known as QDs. Nanocrystals of semiconductor materials that fluoresce when excited by external light sources, primarily in narrow visible and near-infrared regions; they are commonly used as alternatives to organic dyes.
