摘要
通过氧化石墨烯(GO)与无水甲基乙烯基醚-马来酸酐(PMVMA)共聚物组合制备成复合材料(GO-PMVMA),进一步制备出改性葡萄糖氧化物(GOD)电极以得到一新型葡萄糖氧化酶生物传感器。对修饰电极上GOD直接电化学行为的直接伏安法研究表明,复合膜的GOD显示出一对具有良好峰形的可逆峰。进一步研究了新型葡萄糖传感器的电催化行为。葡萄糖线性检测范围为0.4mM^10.8mM,检测限为0.0871mM(S/N=3)。
A composite material(GO-PMVMA) is prepared by combining graphene oxide(GO) with PMVMA, and a modified glucose oxide(GOD) electrode is further prepared to obtain a new glucose oxidase biosensor. Direct voltammetry studies on the direct electrochemical behavior of GOD on modified electrodes show that the GOD of the composite film shows a pair of reversible peaks with good peak shape. The electrocatalytic behavior of the novel glucose sensor was further studied. The linear detection range of glucose was 0.4 mM to 10.8 mM with the limit of detection(LOD) of 0.0871 mM.
