SYNTHESIS AND CHARACTERIZATION OF TIO FOR BIOSENSOR 2 APPLICATION

This paper presents the synthesis and characterization of Titanium dioxide (TiO2) thin film on Indium tin oxide (ITO) coated glass substrates via electrochemical deposition method. The TiO2 thin film was used for immobilizing glucose oxidase (GOx). Which can provide excellent biocompatibility, good electrical conductivity, low electro-chemical interferences and high signal-to-noise ratio for the development of electrochemical biosensors. The morphology and structure of TiO2 were characterized by X-ray diffraction (XRD). Glucose oxidase (GOX) was successfully immobilized on the surface of indium-tin oxide (ITO) electrode modified by TiO2. For the construction of an electrochemical biosensor. The direct electrochemistry and electro-catalytic performance of the biosensors based on TiO2 ware studied by cyclic voltammetry.
