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.||URI:||http://hdl.handle.net/11189/8341||ISSN:||0040-6090||DOI:||https://doi.org/10.1016/j.tsf.2020.138244|
