Facile synthesis of CuO nanostructures for non-enzymatic glucose sensor by modified SILAR method

The authors developed CuO nanorice, using a modified SILAR method for non-enzymatic glucose sensing. The copper oxide was deposited onto the substrate of stainless steel and distinguished by various characterization techniques. A monoclinic structure that is substantially functional for enzyme less glucose sensors have been deposited with polycrystalline CuO. The rice-like morphology of CuO confirms FE-SEM. The electrochemical efficiency of CuO electrodes is calculated by the adoption of cyclic voltammetry (CV) and chronoamperometry (CA) in a 0.1 M NaOH solution with a potential of + 0.6 V (vs. Ag/AgCl). This sensor offers a linear response from 0 to 3 mM to glucose concentration and has a sensitivity of 1017 μAmM−1 cm−2.
