英文摘要:

      Public concerns over pesticide residues in food had been increasing because of their bioaccumulation effects and their great danger to the environments and human’s heath. It was therefore imperative to detect the pesticide residue using all available analytical methods, especially highly sensitive, simple, rapid and low cost. The biosensor detection strategies held a great promise for the detection of agricultural pesticides, attributing to their key features such as high sensitivity, fast response, robustness, low cost, and miniaturization. This paper reviewed the advances in the design and fabrication of biosensor for pesticide detection and their applications in the food and environment safety. Both advantages and drawbacks of these techniques were summarized. Finally, challenges and perspectives in further developing pesticide biosensors were also discussed.
