中文摘要：
利用壳聚糖（CS）对Cu^2＋的配位吸附作用，制得壳聚糖-Cu^2＋复合膜修饰电极，进一步通过Cu^2＋与蛋白质的配位作用，再将葡萄糖氧化酶（GOD）固定在金电板上制得GOD-Cu^2＋CS／Au电极。该酶电极检测葡萄糖的线性范围为0．03～2．5mmol·L^-1,线性相关系数为0．997，检出限（S／N=3）为1μmol·L^-1。以电化学石英晶体微天平（EQCM）技术监测了各修饰过程。
英文摘要：
A chitosan-Cu^2＋ composite film modified Au electrode was prepared through the compleximetric adsorption of Cu^2＋ on chitosan, and glucose oxidase was further compleximetrically adsorbed on the chitosan-Cu^2＋ composite film through metal-protein complexation for fabricating an enzyme electrode. The biosensor exhibited a linear range from 0. 03 to 2. 5 mmol· L^-1 for glucose sensing, with a linear correlation coefficient of 0. 997 and a detection limit of 1 μmol· L^-1 （S/N= 3）. Various modification processes for the enzyme electrode were monitored by the electrochemical quartz crystal microbalance （EQCM） technique.
