摘要:

本文基于碳酸钙–壳聚糖复合纳米材料构建了电化学生物传感器,采用循环伏安法、电化学阻抗法、计时安培法及扫描电镜技术对其进行了表征,研究了氧化还原蛋白质(酶)的直接电化学和电催化特性,建立了检测H2O2的新方法。该研究丰富了生物电分析化学的研究内容,拓展了复合纳米材料的应用范围。

In this paper, a novel electrochemical biosensor was fabricated based on CaCO3-chitosan composite nano- materials, which was characterized by cyclic voltammetry, electrochemical impedance spectroscopy, chronoamperome- try and scanning electron microscopy. The electrochemical behaviors of redox protein (enzyme) were studied in details and the new methods for determination of H2O2 were developed. These studies enriched the study of biological electro- analytical chemistry, expanding the scope of the application of nanocomposites.
