Electrochemical characterization and application of a gold microfabricated device

Abstract

In this study, two designs were proposed for a gold electrochemical device. Both were fabricated using a single mask photolithography process and electrochemically characterized. The best design (device) was further used to integrate the sulfur-doped graphene (S-Gr), as sensing layer for the electrochemical determination of ascorbic acid. The gold WE acted as a very good substrate for the immobilization of S-Gr.
