Abstract

This study aimed to develop porous Cu and Cu-Co coatings using a rapid one-step electrodeposition technique. The coatings were characterized using scanning electron microscopy and x-ray diffraction. Pencil graphite electrodes were utilized as substrates, and the non-enzymatic glucose-sensing capabilities of the coatings were evaluated using cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy. The results demonstrated that the sensor exhibited a wide linear response range and could detect glucose within two concentration ranges (20 μM–1 mM and 1–7.5 mM) at a potential of 0.50 V in 0.1 M NaOH. The fabrication process of the sensing electrodes was straightforward, highlighting the efficiency of Cu-Co porous coatings as a nanocomposite for glucose detection. In summary, the study presents a promising method for the production of efficient glucose sensors with potential applications in various fields.
