石墨烯因具有大的比表面积、完整的?-?共轭结构及良好的生物相容性和优良的导电性能等特性,受到电化学研究者们的广泛关注.然而在应用过程中,本征态石墨烯存在水溶性差、与介质的相互作用较弱、易团聚等问题.通过使用非共价、共价、氮掺杂修饰的方法对石墨烯进行功能化,较好地改善了这一问题,扩展了石墨烯在电化学领域的应用.自2009年首次将功能化石墨烯应用于第三代电化学生物传感器的研究以来,近几年相关研究呈增多的态势.本文系统总结了自2009年以来,功能化石墨烯作为新型电极修饰材料在第三代电化学生物传感器研究中的相关工作,并阐述了其在该领域发展中遇到的问题.
Due to its large specific surface area, complete conjugated structure, good biocompatibility and good electrical conductivity, graphene has attracted much attention from electrochemical researchers. However, in the application process, intrinsic Graphene has the problems of poor water solubility, weak interaction with medium and easy agglomeration, etc. This problem is better solved by functionalizing graphene with non-covalent, covalent, nitrogen-doped modification , Extended the application of graphene in the field of electrochemistry.Firstly, the functional graphene was applied to the third generation of electrochemical biosensors in 2009, and the related researches have been on the increase for a long time.In this paper, In recent years, functionalized graphene as a new electrode modification material in the third generation of electrochemical biosensors related work, and describes its development in this area encountered problems.
