Abstract: The indiscriminate use of pesticides in agricultural field resulted in environmental contamination and posed an incredible risk to human health. Conventional, methods used for pesticide detection have few impediments; thus there is a need to promote the build up such practical sensors that can aptly identify the pesticide residues to check the further absorption of these harmful toxins. This concern pulls our attention towards the development of Biosensors as a conservative device for fast acknowledgement of poisonous chemicals by making the sample preparation, extraction and cleans up methods simpler. Organophosphates and carbamates are broadly used pesticides in the agricultural fields due to their ability to form a stable adduct with enzyme ACHE and inhibit their activity. The change of enzyme activity can provide a peerless measure of target analyte concentration. This paper highlights the essential steps required for the development of biosensor design for monitoring of pesticides based on choice of bioreceptor element, method of immobilization and transducer used.
