Principle of enzyme-linked electrochemical sensors

Abstract

Enzyme-linked biosensing appliances have been extensively utilized over the last two decades and have been demonstrated to be reformer methods in the quantitative and qualitative examinations of a diversity of analyte substrates over a wide range of implementations. Electroanalytical enzyme-linked biosensors are one of the major and mercantile accomplished classes of biosensors. Several supremacies that enzyme-linked biosensors ensure, such as high selectivity, specificity, and sensitivity, chances of miniaturization and portability, cost-performance, and point-of-care diagnostic testing, provide them more and more appealing for investigation focused on food safety control, clinical analysis, or several disease monitoring objectives. Integration of enzymes in the biosensors ensues in the important development of electrochemical biosensor selectivity, detection limit, sensitivity, fast response, stability, and other electroanalytical properties. In this article, it is aimed to give brief information about the enzymes, their usage immobilization techniques, and enzyme-linked electrochemical biosensors. © 2023 Elsevier Inc. All rights reserved.
