中文摘要：
分别以掺杂氧化石墨烯和石墨烯的壳聚糖为功能基体,尿酸为模板分子,采用恒电位技术于玻碳电极表面制备氧化石墨烯-壳聚糖和石墨烯-壳聚糖的分子印迹电化学传感器.同时,利用电化学与波谱技术研究了不同石墨烯掺杂对制备出的传感器灵敏度的影响.表征结果表明：石墨烯的sp2共轭结构的完整性及其在界面的存在形态是导致不同电化学增敏效果的原因.
英文摘要：
Graphene oxide-ehitosan/moleeular imprinting polymers （MIPs） and graphene-chitosan/MIPs sensors were prepared on the surface of glass carbon electrodes by using chitosan doped with graphene oxide and graphene as a functional matrix, uric acid as the template molecule. The effects of graphene on the sensitivity of the developed sensors were investigated via electrochemical and speetroseopie techniques. The obtained results show that sp2 conjugated structure of graphene and the forms of its interface play important roles in the sensitivity enhancement.
