Enzyme Biosensors for the Detection of Environmental Contaminants

Abstract

Today, water body pollution is one of the world?s biggest environmental problems. In this sense, there is a high demand for the design and potential development of new devices for the detection and quantification of pollutants present in the environment. Biosensors are ideal for detecting and measuring environmental pollution reliably, specifically, and sensitively. Among them, electrochemical enzyme biosensors have many advantages such as their high selectivity and sensitivity to the target substrate, which is presented as an opportunity to significantly improve the diagnosis and monitoring of environmental pollutants. The protocol presented in this chapter consists of a technique for monitoring contaminants in surface waters using the enzyme laccase of fungal origin in the formation of an enzyme biosensor.
