Application of Inorganic Layered Materials in Electrochemical Sensors

Abstract

Abstract Inorganic layered materials with low dimensional opened structure and good biological compatibility and stability are considered as one of the most promising materials for immobilizing biomolecules, which can not only adjust the spacing of layers according to guest molecule size to prevent leakage of guest molecule, but also reduce the effects of surrounding elements on immobilized molecules significantly. Moreover, they can promote electron transfer between the enzyme and the electrode. Therefore, the inorganic layered materials have great potential application in electrochemical sensors. This paper reviews the ways of immobilizing guest molecules on inorganic layered materials and the applications and development prospects of the different types of inorganic layered materials including cationic, anionic and nonionic inorganic layered materials in electrochemical sensors.
