Performance of template-assisted electrodeposited Copper/Cobalt bilayered nanowires as an efficient glucose and Uric acid senor

Copper/Cobalt bilayered nanowires (Cu/Co-bilayered NWs) were successfully synthesized on Copper substrate via template-assisted electrodeposition method. The synthesis was done at room temperature (27 degrees C) and the length of the nanowires was controlled by adjusting the deposition time, deposition potential and many other factors. Polycarbonate track-etch membrane of 150 nm hexagonal pore size was used as a template. Structural characteristics were examined using field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction and transmission electron microscope that confirmed the successful formation of Cu/Co-bilayered NWs. Investigation for sensing of Glucose and Uric Acid was carried out using electrochemical sensing. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods confirmed the successful detection of Glucose and Uric acid in a phosphate buffer solution. The real sample (sugarcane juice) was also tested to sense the presence of glucose using synthesized nanowires. The results proved that synthesized nanowires can be an economical sensor with great performance and sensitivity.
