上转换发光纳米材料在生物成像中应用的研究进展

Research progress in upconversion nanophosphors for biological imaging

稀土上转换发光纳米材料是一类利用近红外光激发而短波长发射的荧光材料,因其具有发光性质稳定、无光漂白现象、弱的生物样品损伤和高荧光信噪比等优点,在荧光成像中可弥补传统荧光标记材料的不足而发挥重要作用.本文重点介绍上转换发光纳米材料在生物成像中应用的进展.

The upconversion nanophosphors are a kind of fluorescence materials with near infrared excitation and short wavelength emission. The upconversion nanophosphors can compensate for the deficiencies of the traditional fluorescent labeling materials because of the stability, non-photobleaching, weak photodamage of biological samples, and high fluorescence signal to noise ratio of biological samples. This review focuses on the upconversion nanophosphors in bioimaging applications.
