中文摘要：

作为单原子厚度的二维碳原子材料,石墨烯由于其特殊的结构和理化性能而成为目前碳基材料中的一个研究热点。为了进一步拓宽石墨烯的应用范围和提高石墨烯的应用能力,需要对石墨烯或其衍生物进行功能化修饰。本文主要综述了石墨烯的功能化方法及功能化石墨烯基纳米复合材料在电化学生物传感应用领域的研究进展。

英文摘要：

Graphene, as a two - dimensional carbon material with a single layer of carbon atoms, has become a research focus of carbon based materials because of its unique structure, physical and chemical properties. In order to further broaden the range of graphene applications and improve the application capacity of graphene, graphene or its derivatives need to be functionalized. In this paper, the functionalization methods and the progress of functional graphene based nanocomposites in the application for electrochemical biosensing are reviewed.
