Abstract: CuO nanoparticle functionalized thin film electrode has been fabricated on fluorine doped tin oxide coated conductive glass using an efficient facile solution deposition technique for non-enzymatic electrochemical detection of glucose. The CuO nanoparticulate thin film exhibited an excellent electrochemical response towards glucose oxidation, high sensitivity of 1207 μA mM−1 cm−2, a linear range of up to 2,2 mM, and fast response of less than 4 s at a potential of 0,55 V vs Ag/AgCl with a limit of detection calculated to be 1,19 μM (at a signal-tonoise ratio (S/N) of 3). The prepared sensor exhibited exceptional selectivity to multiple interference species, satisfactory reproducibility and excellent chemical stability. The performance demonstrated makes the electrode material promising for the development of effective non-enzymatic glucose sensor.
