Biosensors for monitoring environmental pollutants: A review

S.Gayathri, Judith M.Braganca

Biosensors are used to identify and monitor different types of pollutants and its effect on the ecosystem. The nature of pollutants, their source and bioavailability can be identified with a high level of specificity and sensitivity with the help of the biosensors. Various biosensors used in pollutant studies for monitoring eutrophication, food safety, detection of pathogenic microorganisms, tracemetals, pesticides, herbicides and organic wastes are analysed.
