Quantum dots for single bio-molecule imaging

The emerging nanomaterial, quantum dots or QDs, offers numerous potential applications in the biological at-ea. As cell labeling probes, QDs become now an alternative of existing organic fluorescent dyes and fluorescent proteins. In this short review, we cover typical and successful applications of QDs as fluorescent probes in cell labeling and genomic diagnosis. As a future important application, biomolecular detection at,a single molecule level utilizing QDs is also discussed.
