Abstract: Near-infrared (NIR) fluorescence is superior for in vivo ultrasensitive and multiplex biological imaging because it could provide much higher imaging depth and signal-to-noise ratio than visible fluorescence. Here we reviewed the research progress of composition-dependent and structure-dependent NIR-emitting quantum dots (QDs). Furthermore, the multiple tuning of NIR fluorescence spectrum and the development of non-toxic QDs were pointed out.
