In the world of fluorescent labels, organic dyes are out, and quantum dots (QDs) are in. These nanosize crystals of semiconducting material (typically CdSe) sport a broad excitation profile, strong fluorescence, enviable photostability, and narrow, size-dependent emission spectra. QDs are ideally suited for most multiplexed fluorescence applications, but not for fluorescence resonance energy transfer (FRET).
