摘　　要：阻抗型免疫传感器是利用抗原(或抗体)在电极表面发生特异性结合前后导致电极表面的电化学性质发生改变而实现对抗体(或抗原)进行测定一类新型免疫传感器,其具有制备简单、响应时间短和灵敏度高等特点。该文对阻抗型免疫传感器的工作原理,发展及现阶段的应用进行了综述,并对未来的发展趋势进行了展望。Electrochemical impedance spectroscopy immunosensor was based on the specific binding between bio- logical molecules on the electrode surface to change the electrochemical properties of the electrode, so as to determi- nation of biological molecules, which possesses simple preparation, short response time and high sensitivity charac- teristics. The working principle, current development and application of the electrochemical impedance spectroscopy immunosensor are summarized in this review, and the latest technological challenges and future development trend is prospected.
