Abstract
Galvanostatic electrodeposition of copper foil was performed in the presence of 2-Acrylamido-2-methylpropanesulfonic acid (AMPS) to obtain an electrochemical sensor for sensitive and selective glucose detection. Electrochemical performances of as-prepared enzyme-free electrodes were evaluated using chronoamperometry, cyclic voltammetry and impedance spectroscopy in 0.1 M NaOH solution. The results revealed that a detection limit of 0.98 μM is obtained along with a linearity of 7–48 μM for glucose sensing. The interference studies show that good selectivity was obtained in the presence of fructose, sucrose, lactic acid, ascorbic acid, urea etc.
