摘　　要：量子点(Quantum Dots,QDs)是一种半导体纳米微晶,具有光稳点性好、激发光谱宽而连续、发射光谱窄而对称、荧光寿命长等优点,被广泛应用于生物标记、传感和成像等应用中,水溶性量子点表面带有功能基团,能够与抗体发生偶联,本文着重从共价和非共价偶联两个方面来进行分析,同时对量子点的前景进行展望.Quantum Dots ,a kind of semiconductor nanomaterials,are known as its unique advantages,including sig-nal stability,long fluorescence lifetime. The excitation spectrum is wide and continuous,while the emission spectrum is narrow and symmetric. QDs are widely used in biological labeling,sensing,imaging areas. The hydrosoluble quan-tum dots have many functional groups on surface,and could be conjugated with antibody. We mainly discussed about the methods applied in quantum dots conjugation.
