Abstract: Abstract: As emerging promising fluorescent labels， semiconductor quantum dots (QDs) have  tremendous potential in the fields of biology and medicine because of their unique optical properties with size-tunable light emission， broad absorption spectra for simultaneous excitation of multiple fluorescence colors， superior signal brightness， resistance against photobleaching， etc. This article briefly discusses the recent progresses on fluorescent QDs probes and their biological labeling including their surface modification and functionalization.
Key words: fluorescent quantum dots; probe; biological labeling
