Abstract :Herein, the copper-based electrodes were successfully synthesized with galvanostatic electrodeposition method. The effect of materials obtained at different concentrations of ASA and anodization times on glucose sensing ability was investigated. During the anodization of copper foil in the presence of ASA molecules, it formed a tree branch-like structure connected to each other while decorating the electrode surface. The Cuinsert ignore into journalissuearticles values(30);/ASAinsert ignore into journalissuearticles values(0.02); electrode exhibited a relatively wide linear range insert ignore into journalissuearticles values(0.2 – 10.0 mM); and a low detection limit insert ignore into journalissuearticles values(0.826 µM);. These excellent activities were mainly attributed to the surface morphology, which functions as highly active sites and enhanced electronic conductive pathways with the addition of ASA. In addition, the stability obtained together with the excellent sensing ability in beverages makes the electrodes useful for practical applications.
