摘要
比率式荧光传感通过在同一传感基质中掺杂两种或两种以上对分析物具有不同响应的发光体,根据不同的光发射信号比值构建起来的光化学传感体系,能更好满足实际检测的需要。近年来,比率式荧光纳米传感器的构建已引起了人们的广泛关注。该文介绍了比率式荧光纳米氧传感器的制备方法、传感特性和应用情况,并对其传感检测的发展和应用前景进行了分析和展望。
Ratiometric sensing nanoprobes derivatized from luminescent dyes show great application in a nano or micro system as well as in a sensing material. Nowadays,a ratiometric nano sensing system has attracted a wide variety of attentions. In this review,the meaning of measuring oxygen concentration was introduced and the determination approaches for O_2 was discussed. The research progress of nanosensors for O_2 based on ratiometric fluorescence including their preparation,characteristics and applications,was systematically reviewed.
