Coated Carbon Nanotubes at Nano Copper Modified GCE for Simultaneous Determination of Dopamine and Uric Acid

Abstract:

Copper (Cu) nanoparticles have been electrochemically deposited onto the glassy carbon electrode (GCE) surface by potentiostatic deposition method and then carbon nanotubes (CNTs) was dropped on the nano-Cu modified electrode surface to get a CNTs/nano-Cu/GCE electrode. The CNTs/nano-Cu/GCE has shown much higher electrocatalytic activity than the CNTs/GCE towards the oxidation of dopamine (DA) and uric acid (UA) in a phosphate buffer solution (pH 6.9). It can be applied to determine DA and UA with satisfactory results.
