Au nanoparticles modified CuO nanowireelectrode based non-enzymatic glucose detection with improved linearity.

ABSTRACT: This paper explores gold nanoparticle (GNP) modified copper oxide nanowires(CuO NWs)based electrode grown on copper foil for non-enzymatic glucose detection in a wide linear ranging up to 31.06 mM, and 44.36 mM at 0.5 M NaOH and 1 M NaOH concentrations. The proposed electrode can be used to detect a very low glucose concentration of 0.3 µM with a high linearity range of 44.36mM and sensitivity of 1591.44 µA mM^-1 cm^-2. The electrode is fabricated by first synthesizing Cu (OH)₂ NWs on a copper foil by chemical etching method and then heat treatment is performed to convert Cu (OH)₂ NWs into CuO NWs. The GNPs are deposited on CuO NWs to enhance the effective surface-to-volume ratio of the electrode with improved catalytic activity. The surface morpho
