window, graphene and posites had been used as a carrier material for biosensors. It is
e one of the hottest electrochemical material, owned broad application prospects.
Electrochemists had been exploited a variety of methods using grapene and posites to make
biosensor electrodes for the detection of living matter. In this article, progress of graphene and its
composites for biosensor electrode is summarized. The development direction and prospect were
also discussed.
Key words: graphene; posites; biosensors; modified electrode; progress

石墨烯(graphene)是由单原子层碳以 sp2 杂化轨道组成的一种二维碳纳米材料[1-3]。石
墨烯中的碳原子以六角型紧密堆积蜂窝状排列,结构十分稳定。石墨烯是其它维度石墨材料
的基本构建模块,它可以被包装成零维的富勒烯,卷成一维的碳纳米管或者堆叠成三维的金
刚石或石墨。石墨烯
