Review: Advances in Biosensor-Based Instruments for Pesticide Residues Rapid Detection

The food safety issues associated with the presence of pesticide residues in agriculture products have raised the need of pesticide residues detection instrument to detect pesticide residues rapidly, sensitively and online in different commodities. The measurements of specific biological-recognition that coupled with a signal transducer were the principle to realize the detection. Instruments based on biosensors for pesticide residues detection have shown advantage and broad application prospects in the instrument market. The present overview is an effort to review the various transduction systems and biosensor devices so far in the development of pesticide residues rapid detection instrument based on biosensors, such as electrochemical biosensors, optical biosensors and mass-based biosensors. Furthermore, miniaturization, stability, sensitivity, repeatability and signal intensity of the biosensors and applications of these biosensors were evaluated in the development of biosensor instruments. Recent advances about pesticide residues detection with different types of biosensors have been analyzed and summed, which was shown that with the development of biosensors for detection monitoring, corresponding biosensor instruments are also becoming one essential tool in society with low cost and to make the pesticide residues detection foolproof.
