Electrochemical biosensors based on peroxidase: A review

Biosensors are devices that use biological components as recognition elements. Most of the biosensors available on the market are electrochemical because they are small and simple to operate. Currently, peroxidase is one of the main enzymes used in studies of biosensors. It catalyzes chemical reactions of several phenolic compounds. There is a great expectation for the creation of biosensors using peroxidase enzyme because of the importance of electrochemical biosensors and the good characteristics of this enzyme, which increases the number of scientific articles published on electrochemical peroxidase biosensors. This review describes the characteristics of electrochemical biosensors, adding new technologies that have emerged in recent years and that promise to revolutionize the biorecognition. (author)
