Abstract: In recent years, efforts have been reported to develop portable biosensor instrument in the detection felid such like pesticide residues. There is a great potential in the applications of biosensor technologies for rapid detection of pesticide residues in food and environment. In other words, meantime, biosensor instrument has wide application in the instruments market. This paper presents an overview of various transduction systems of instruments, such as based on electrochemical, optical, piezoelectric, and nanomechanics methods' biosensor instruments, which have been reported in the literature in the design and presentation of biosensor instruments for pesticide detection. Various immobilization protocols used for formation of a biorecognition interface are also discussed. Moreover, in the design of biosensor instruments, regeneration technology, include signal amplification, miniaturization, and biosensor devices are evaluated for the development and applications of these biosensors. It can be concluded that despite some limitations of the pesticide residues detection technologies, these biosensors for pesticide monitoring are becoming more and more relevant in environmental and food analysis, that is to say, with the development of means of biosensors for detection monitoring , corresponding biosensor instruments are also becoming one essential tools in society.


Keywords: Electrochenmical biosensor, Optical biosensor, Biosensor instruments, Pesticide residues.
