Original Abstract

t3D-printed stainless steel helical shaped electrodes with or without surface modification with a gold (Au)film are tested as novel electrode materials for the electrochemical detection of ascorbic acid and uric acidin aqueous solutions. Their performance in terms of sensitivity, selectivity and reproducibility is evaluatedand compared to conventional glassy carbon electrode (GCE). Owing to the excellent electrocatalyticproperties of the 3D-printed gold (Au) electrode, a clear separation between the anodic oxidation signalof ascorbic acid and uric acid in differential pulse voltammogram (DPV) could be obtained, allowingsimultaneous quantification of these biomarkers. The oxidation current obtained using the 3D-printedAu electrode increased linearly with its respective biomarkers concentration in the range of 0.1–1 mM.Furthermore, the 3D-printed Au electrode generally performed better in terms of sensitivity and detectionlimits as compared to GCE. A real sample analysis of Vitamin C tablet (500 mg), Vitacimin was conductedusing the 3D-printed Au electrode obtaining a variation from claimed concentration of ascorbic acidof only about 0.5%. Therefore, electrodes fabricated by 3D printing would certainly represent a viablealternative to conventional electrodes for efficient electrochemical analysis in the future.
