Application of Inorganic Layered Materials in Electrochemical Sensors / 分析化学

ABSTRACT

Inorganic layered materials with the open structure of low dimension 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 molecular 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 enzyme and the electrode. Therefore, the inorganic layered materials have great application potential in electrochemical sensors. This paper reviews the ways of immobilizing guest molecules of 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 sensor.
