摘要
血红蛋白在裸电极上电子传递速率很慢,难以发生明显的电化学信号,采用媒介体可以加快电极上电子传递速率。文章综述了纳米修饰电极、类生物膜修饰电极、离子液体膜修饰电极等修饰电极的稳定性以及对血红蛋白活性的影响,阐述了修饰电极对血红蛋白催化还原的影响。
The direct electron transfer between hemoglobin and the bare electrode is rather slow,while can hardly appear obvious electrochemical signals. Using mediators could speed up the electron transfer. This paper introduces the stability of nanoparticles electrode,simulation biomembrane electrode,carbon ionic liquid electrode and others;also reports the effect of nature of hemoglobin. The electrochemistry and electrocatalysis of hemoglobin on modfied electrodes are investigated.
