Abstract
Pesticides have played an important role in agricultural production as an effective means of rapid and efficient control of pests and diseases. However, their unreasonable use can lead to excessive pesticide residues in the environment and agricultural products, posing a great threat to the ecological environment and human health. Therefore, it is necessary to establish a new technique for pesticide residue analysis that is efficient, sensitive and practical. Electrochemical sensors are widely used in the detection of pesticide residues due to their high sensitivity, stability, selectivity, simplicity, fast speed and low cost. This article reviews the application and research progress of immuno, enzyme, nano and molecularly imprinted electrochemical sensors in pesticide residue detection, and gives an outlook on the future application of electrochemical sensors in pesticide residues detection.
