Quantum Dots Antibody Coupling Research Progress

Quantum Dots,a kind of semiconductor nanomaterials,are known as its unique advantages,including signal 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 quantum dots have many functional groups on surface,and could be conjugated with antibody. We mainly discussed about the methods applied in quantum dots conjugation.
