英文摘要：

Being a novel two-dimensional carbonous nanomaterial, graphene has recently attracted considerable attention because of its unique structure and distinct properties. The significantly high conductivity, large surface area and perfect biocompatibility make graphene and its composites favorable in the construction of enzymatic electrochemical biosensors. This review presents a general description of the functionalization of graphene. In particular, the recent application of graphene nanomaterial in the field of enzymatic biosensors is summarized.
