Electrochemical immunosensor used for CLB detection, and preparation method thereof

The invention provides an electrochemical immunosensor used for CLB detection, and a preparation method thereof. The electrochemical immunosensor possesses a working electrode based on a MoS2-AuPt nanometer composite and a biotin-streptavidin system. The electrochemical immunosensor is high in sensitivity (detection limit is 6.86pg.ml), the specificity is high, the repeatability is acceptable,and the electrochemical immunosensor can be used for detection of practical pork samples. 本发明提供种用于CLB检测的电化学免疫传感器及制备方法，该电化学免疫传感器具有基于MoS-AuPt纳米复合物和生物素-链霉亲和素系统的工作电极，本发明所提出的电化学免疫传感器具有良好的灵敏度(检测限为6.86pg·mL)，高特异性，可接受的重复性，同时也可用于实际猪肉样品中的检测。
