血红蛋白是脊椎动物红细胞内的呼吸蛋白,但由于其电活性中心不容易暴露以及在电极表面强烈吸附造成电极的钝化,使得它在一般固体电极上的电子传递速率很慢,得不到有效的电流响应。有关血红蛋白在固体电极上的电化学行为的研究很少。众多的分析化学家都在积极寻求加速血红蛋白电子传递速度的途径,使蛋白质直接电化学分析成为可能。最近的研究表明,某些染料修饰电极可以促进血红蛋白的电极过程,从而获得有效的电流响 Hemoglobin is a respiratory protein in vertebrate erythrocytes. However, due to its electroactive center is not easily exposed and the electrode is strongly adsorbed on the electrode, hemoglobin is passivated by electrons. Therefore, the electron transfer rate of hemoglobin is very slow on general solid electrodes, and no effective Current response. Little is known about the electrochemical behavior of hemoglobin on solid electrodes. Many analytical chemists are actively looking for ways to accelerate the rate of hemoglobin electron transfer, making direct electrochemical analysis of proteins possible. Recent studies have shown that certain dye-modified electrodes can promote the hemoglobin electrode process to obtain an effective current
