As the population grows, demand for food is rising. However, the food harvest is not very stable because of adverse factors such as insect disasters and drought. To ensure adequate food production, people used pesticides to ensure the growth of crops. Many crops have been harvested, followed by varying degrees of pesticide problems, leading to important global health problems. Although traditional technologies such as high performance liquid chromatography (HPLC) and mass spectrometry (MS) have traditionally been used to detect such food pollutants, they are relatively expensive, timeconsuming, and labor-intensive. For this reason, a simple and sensitive method for the detection of pesticides is urgently needed. Electrochemical biosensors are emerging devices to meet this expectation because they represent reliability, simplicity and cheapness. In this review, we discussed the use of electrochemical biosensors to detect four categories of pesticides and further summarized the advantages of such a detection method for detecting pesticides.
