A shining example : We report a facile strategy to synthesize highly luminescent, water‐soluble, and biocompatible CdTe nanocrystals by using the biomolecule glutathione as a stabilizer. The highest quantum yield obtained was above 60 % and their size‐dependent emission ranged from 480 to 650 nm. The nanocrystals could be coupled with antibodies to prepare fluorescent probes for cell imaging (see figure).
