| Abstract: | ABSTRACT: The aim of this study was to prepare three types of multi-wall carbon nanotube (CNT)-based composite electrodes and to modify their surface by copper electrodeposition for non-enzymatic oxidation and determination of glucose from aqueous solution. Copper decorated multi-wall carbon nanotube composite electrode (Cu/CNT-Epoxy) exhibited the highest sensitivity to glucose determination. The reliability of the Cu/CNT-Epoxy electrode was verified by application of this composite electrode for the determination of glucose in real blood serum samples. |
