Electrochemical Biosensors for the Detection of Pesticides

摘要

Biosensors have been developed for the detection of pesticides using integrated enzymes, antibodies, cell andDNA-based biosensors. Enzymatic determination of pesticides is most often based on inhibition of the activity of selectedenzymes such as cholinesterase, acid phosphatase, ascorbate oxidase, acetolactate synthase and aldehyde dehydrogenase.Enzymatic Biosensors were developed using various electrochemical signal transducers and different electrodes. Variousimmobilization protocols used for the formation of a biorecognition interface are also discussed: In addition, techniques ofregeneration, single amplification, and miniaturization are evaluated for the development of immunosensor. Both batchand flow-injection analyses with enzyme biosensors are most intensively developed. It included that, in the future, compact,disposable and portable devices especially designed for in-field analysis with high sensitivity, selectivity; developmentof arrays and multiple sensors will continue another area of intensive research for biosensors.
