Abstract

We investigated the electrochemical behavior of hemoglobin by glassy carbon electrode modified with Mn(2)O(3)-Ag nanofibers. The Mn(2)O(3)-Ag nanofibers were used as facilitator electron transfer between Hb and glassy-carbon-modified electrode. The Mn(2)O(3)-Ag nanofibers are studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The hemoglobin showed a quasireversible electrochemical redox behavior with a formal potential of -49 mV (versus Ag/AgCl) in 0.1 M potassium phosphate buffer solution at pH 7.0. The designed biosensor possesses good stability and reproducibility and achieves 95% of the steady-state current in less than five seconds.

摘要

我们研究了用Mn₂O₃ - Ag纳米纤维修饰的玻碳电极上血红蛋白的电化学行为。Mn₂O₃ - Ag纳米纤维用作血红蛋白与玻碳修饰电极之间的电子转移促进剂。通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）对Mn₂O₃ - Ag纳米纤维进行了研究。在pH 7.0的0.1 M磷酸钾缓冲溶液中，血红蛋白呈现出准可逆的电化学氧化还原行为，其形式电位为 - 49 mV（相对于Ag/AgCl）。所设计的生物传感器具有良好的稳定性和重现性，并且在不到五秒的时间内达到稳态电流的95%。
