Abstract:

Due to the high sensitivity, fast response, less sample usage, and simple operation, microelectrodes have attracted increasing attention in the fields of chemical analysis, biomedicine, food safety and environmental monitor recently. Given its high specific surface area, excellent electron mobility and good biocompatibility, graphene has shown a huge development potential in the field of electrochemical sensing. This review summarizes recent advances in the preparations and applications of graphene-based microelectrodes(including graphene modified microelectrode and graphene microelectrode) in sensing, such as the detection of heavy metal ions, dopamine, glucose, H2O2 and other molecules. Simultaneously, the major problems and opportunities of these graphene-based microelectrodes in sensing for future development are also discussed.

Key words: graphene, microelectrode, electrochemical sensing
