摘　　要：由于石墨烯或其衍生物具有的独特的电、热、机械、光及电化学性能,特别是单层石墨烯或其衍生物极高的载流子迁移率、良好的导电性、高比表面积、易于功能化、强荧光猝灭性和生物分子亲和力,尤适于生物传感系统的构建。本文对近几年来石墨烯及其衍生物在场效应晶体管、电化学、压电晶体、光致发光及电化学发光生物传感系统方面的研究情况进行了综述。Graphene and its derivatives have recently attracted considerable attention because of their vast array of distinct electronic,thermal,mechanical,optical,and electrochemical properties.Thus, this set of compounds has become a research hotspot and a promising area for scientific research.The significantly high carrier mobility,high electrical conductivity,high surface area,ease of functionalization, strong fluorescence quenching,and affinity for biomolecules make graphene and its derivatives suitable in the development of biosensing systems.In our review,we describe the recent applications of graphene and its derivatives to field-effect transistors as well as to electrochemical,piezoelectric, photoluminescence,and electrochemiluminescence biosensing systems.
