核酸作为生物体遗传信息的载体以及分子生物学和生物分析化学中重要的功能分子，近年来在电化学分析中受到了越来越多的重视。本文以作者所在研究组的工作为实例，对核酸分子识别的电化学分析方法作出简要的评述，内容涉及核酸序列和基因变异的电化学分析以及核酸作为功能分子进行识别检测的电化学分析等等。

Nucleic acid as the carrier of genetic information and the functional molecules for molecular biology and bioanalytical chemistry has attracted increasing interest in electrochemical analysis. This review presents a brief outline of some electrochemical analytical assays based on molecular recognition of nucleic acids. Most of these methods are focused on the detection of nucleic acid sequence, genetic mutation and nucleic acids as functional molecules.
