Glucose sensing characterisations of TiO₂/CuO nanofibres synthesised by electrospinning

Abstract

Glucose detection is important in the fields of environmental, biological and clinical analyses. In our study, TiO2/CuO nanofibre (NF) electrode prepared by electrospinning was applied to construct a non-enzymatic glucose sensor. The TiO2/CuO NFs were characterised by X-ray diffraction, scanning electron microscopy and transmission electron microscope. Glucose sensing characterisations were studied by cyclic voltammetry and chronoamperometry. For amperometric glucose detection, the detection limit of 10 μM (S/N = 3) with linear range from 10 to 3600 μM can be obtained using the TiO2/CuO NF electrode. It is believed that the TiO2/CuO NF electrode is a promising material for the development of non-enzymatic electrochemical glucose sensors with excellent biocompatibility.
