一、前言自1967年第一支酶电极问世以来,数以百计的各种生物电化学传感器相继出现,为临床检验、环境分析、食品、医药等工业生产过程的监控提供了新的工具。虽然在国内,有关的研究开发工作起步较晚,但已引起人们的重视。研制生物传感器要解决的一个重要问题,即酶的固定化并保持其活性,使生物传感器既有高的响应灵敏度,又要有长的使用寿命。针对这一问题,我们进行了一系列理论和应用的研究。现在葡萄糖酶电极的研究较普遍,但葡萄糖酶电极并没有直接在血糖测定中得到应用,这是因为在用它测定血液中的葡萄糖浓度时,电极寿命短,响应电流不稳定,
I. Introduction Since the advent of the first enzyme electrode in 1967, hundreds of various kinds of bioelectrochemical sensors have emerged one after another, providing new tools for the monitoring of clinical testing, environmental analysis, food, pharmaceutical and other industrial processes. Although in China, the research and development work started relatively late, it has drawn people’s attention. The development of biosensors to solve an important issue, that enzyme immobilization and maintain its activity, the biosensors have both high response sensitivity, but also have a long life. In response to this problem, we conducted a series of theoretical and applied research. Glucose enzyme electrode is now more common, but glucose electrode is not directly used in blood glucose measurement, because when using it to measure blood glucose concentration, electrode life is short, the response current instability,
