电化学作为现代仪器分析重要的组成部分，在生命科学领域正扮演着越来越重要的角色.随着蛋白膜伏安法（protein film voltammetery,PFV）的不断完善，以及表面修饰技术、纳米技术、分子标记与分子识别技术等相关技术的不断发展，在蛋白酶研究领域，电化学正逐渐克服以往手段较为单一、研究目标不够多样、获取信息不够丰富等弊端.以本课题组在该领域所取得的一些研究成果为主，综述蛋白酶电化学研究的现状和发展趋势.

Electrochemistry has become increasingly important in the study of life sciences. With the development of protein film voltammetry (PFV) and advances in surface modification, nanotechnology, molecular recognition and molecular marker, electrochemistry has overcome some drawbacks in protein enzyme studies. This article summarizes some typical work of the group, and reviews the progress in the electrochemical study of protein enzymes.
