摘　　要：氧化石墨烯因其独特的光学、表面、机械、电学及热学性质在诸多领域都具有良好的应用前景。利用氧化石墨烯能够有效猝灭荧光体(染料分子、量子点及上转换纳米材料)荧光的特性,结合相关生物分析技术,相继开发了各种荧光传感器。本文综述近年来氧化石墨烯荧光传感器的基本原理及研究进展,主要讨论氧化石墨烯荧光传感器在重金属离子、DNA、蛋白质及生物小分子的分析应用,并对该领域的应用前景进行了展望。Graphene oxide has great application prospect in many fields due to its unique optical, high surface area, exceptional electronic, thermal and mechanical properties. Taking advantage of the property that graphene oxide can effectively quench the fluorescence of fluorophor including dye, quantum dot and upconversion nanophosphors and various bioanalytical technology, many fluorescent sensors have been developed. In this review, we summarized the principle of fluorescent sensors based on graphene oxide and their application in heavy metallic ion, DNA, protein and small bio-molecule. Moreover, the trends and future perspectives in this research area are also briefly discussed.
