Studies on Biosensing Properties of Electrodeposited Copper Oxide Films

Abstract

The copper oxide (CuO) based films have been prepared for biosensing application. Electrodeposition mode has been used for preparation of CuO films on cost effective stainless steel substrates. The structural properties of CuO material are studied by X‐ray diffraction (XRD) pattern and it shows (ī11) more intensive plane. Hierarchical multilayer nanosheets clusters have been displayed in scanning electron microscopic images. The energy dispersive X‐ray analysis (EDAX) pattern displays wt% of Cu and oxygen in CuO material and it is found to be 52.80% and 57.61%. The glucose sensing of CuO electrodes is carried out in NaOH and glucose electrolyte at different concentration of glucose and 10–50 mV s−1 scan rates. The effect of glucose sensing on CuO electrode has been studied.
