Quantum Dots Optically Code Biomolecules

Daniel C. McCarthy

Chemists at Indiana University have taught quantum dots to fear water. And that's a good thing. For the past three years, several research groups have developed these nanometer-scale, semiconductor-based crystals as a potential alternative to the organic dyes used as tags in biological assays. Unlike quantum dots, dyes can be toxic and more prone to photobleaching, and require multiple light sources to fluoresce multiple dyes. Most quantum dots developed in the past were water-soluble (hydrophilic), which presented problems in guiding and bonding the dots to target molecules. However, by...Read full article
