摘要: 将葡萄糖氧化酶(GOD)固定在α-环糊精聚合物中,而电子传递体分子被包含在环糊精腔穴中。固定化酶膜的FTIR测定表明,GOD与环糊精聚合物发生共价连接。制备了含电子传递体的不同GOD酶电极并比较了它们的性能。含四硫代富瓦烯的酶电极具有良好的电流响应特性,可望成为第二代葡萄糖酶电极的新构型。

Abstract: This paper describes a new design of glucose enzyme sensor in which glucose oxidase(GOD)is immobilized in a condensation α-cyclodextrin polymer membrane and a mediator is molecularly included in the cyclodextrin cavity.The FTIRmeasurement of the immobilized enzyme membrane indicated that GODwas attached to the cyclodextrin polymer by covalent bonding.The different GODenzyme electrodes with mediators were prepared and their performances were compared.The GODelectrode with tetrathiafulvalene showed good amperometric response to glucose in test solution, and promised well to be the second generation glucosesensor.
