Copper Sulfide Materials for Nonenzymatic Glucose Detection

Abstract

Copper sulfide materials were prepared by solvothermal technique. The structural and morphological characterization of obtained semiconductors was carried out using Scanning Electron Microscopy and X-ray diffraction method. Flower_like Cu _1.8 S was immobilized on glassy carbon electrode to construct nonenzymatic glucose sensor. Electrochemical behavior of modified electrode toward glucose was examined by cyclic voltammetry in alkaline aqueous solution. Glucose sensor exhibits a good response, high sensitivity and low detection limit for electrocatalytic oxidation of glucose.
