This paper analyzes the detection mechanism of electrochemical sensor by integrating nanotechnology with electrochemical analysis, and achieves excellent detection results after applying the proposed method to detect the clenbuterol (CB) and chloramphenicol (CAP) in food. Specifically, the modified electrode and Cu-Au marked CB antibody are prepared in this research and the detection method of electrochemical sensor is optimized. The results show that the proposed method realizes the rapid detection of CB in food. The detection range falls between 0.1 and 500ng/ml and the detection limit reaches 0.05ng/ml. The proposed method is also adopted for the treatment of samples of actual pig liver. According to the detection results, the recovery rate is between 94.25% and 101.14%. For the detection of CAP, the electrochemical sensor boasts advantages like wide detection range and low detection limit, and the results obtained by the sensor shows no significant difference from those obtained by the traditional high-performance liquid chromatography. Thus, the proposed detection method is proved to be accurate and fast.
