Electrochemical Biosensors for Determination of Organophosphorus Compounds: Review

摘要

In last few decades there is exponential increase in use of organophosphorus (OP) compounds as pesticides and insecticides leading to adverse effect on human population and live stock. There is a great need to develop portable analytical tools that are amenable for remediation and bioremediation process monitoring, where rapid analysis of large number of samples is essential. Determination of various organophosphorus compounds has been achieved by integrating biocomponents with different transducers. The close integration of the biological events with the generation of a signal offers the potential for fabricating compact and easy-to-use analytical tools of high sensitivity and specificity. With the availability of new materials, associated with new sensing techniques has led to remarkable innovations in the design and construction of organophosphorus biosensors. The present review describes the specifications of most of the electrochemical Organophosphorus biosensors reported till date.
