Recent advances in ZnO nanostruture based electrochemical sensors and biosensors

Abstract

Recently, nanostructured metal oxides such as zinc oxide (ZnO) are considered as excellent material for fabrication of highly sensitive and selective electrochemical sensors and biosensors due to good properties including high specific surface area, high catalytic efficiency, strong adsorption ability, high isoelectric point (IEP, 9.5), wide band gap (3.2 eV), biocompatibility and high electron communication features. Thus, ZnO nanostructures are widely used to fabricate efficient electrochemical sensors and biosensors for the detection of various analytes. In This review, the synthesis of ZnO nanostructures and recent advances in various ZnO nanostructures based electrochemical sensors and biosensors for medical diagnosis, pharmaceutical analysis, food safety, and environmental pollution monitoring, are discussed.
