Screen Printing Preparation of Porous Cu Integrated Electrode as a High Sensitivity Enzyme-Free Glucose Sensor

Abstract Herein, a three-electrode coplanar integrated electrode was prepared by the screen-printing process. By designing reasonable structure, scheme for preparation of Cu (OH) 2 /Ag/AgCl/C/Al O 3 screen printing proposed. The morphological structure material investigated SEM, EDS, and XRD characterization methods. Moreover, availability electrodes characterized macroscopically using an electrochemical workstation. As results showed, innovative sensor exhibited excellent detection performance catalytic oxidation glucose. Electrode sensitivity up to 14.376 mA mM −1 cm −2 in glucose range 1 μM–0.05 mM, while, interference immunity reproducibility were achieved.
