摘要:
量子点是一种三维纳米晶粒，具有许多优异的光学性能，如激发波长范围宽、发射波长范围窄且对称、量子产率高、荧光寿命长、光学性能稳定等优点。量子点可以作为荧光探针来标记生物体系的不同成分，如组织、细胞、生物大分子以及动物活体成像，本文就量子点在生物医学领域作为荧光标记物的研究进展加以综述。
Quantum dots (QDs), three-dimensional (3-D) nanocrystals, possess a great deal of unique optical performances, such as wide excitation wavelength, narrow and symmetric emission wavelength, high quantum yield, long fluorescence lifespan, stable optical property. QDs can be used as fluorescent probes to label different components in biosystem, which contains tissues, cells, molecules and living animals imaging. A review on the advances of QDs as fluorescent probes in Biological and Medical fields is given in the paper.
