Abstract:
Semiconductor quantum dots (QDs) are a new kind of biological fluorescence material, which has many advantages, such as broad excitation spectra, tunable emission spectra and good photostability. In the field of biomedical detection, the problems encountered in the traditional organic dye-based biomedical detections, such as short fluorescence lifetime and failure to simultaneous excitation of multiple colors, can be solved by using QDs. Water-soluble QDs combined with specific bio-molecules can label targeting bio-compound, which is useful in bio-molecule detection, cell labeling, tissue imaging, and can be used in fluorescence resonance energy transfer (FRET) technology. Combining QDs and protein chip technology to develop a new technology to detect multiple kinds of tumor markers will be one of the promising clinical applications of QDs with greater sensitivity, specificity, rapidity and convenience.
