Electrochemical sensors cleaned by light: a proof of concept for on site applications towards integrated monitoring systems†
Abstract
The potential for on site applications of a SiO2–Ag NPs–TiO2 self-cleaning electrode was demonstrated. Dopamine was used both as the analyte and the fouling agent. Three different UV lamps (a powerful lamp (45 mW cm−2) for photocatalysis, a TLC lamp and a commercial LED torch) were studied. After fouling, total recovery of the electroanalytical performances was achieved upon a short irradiation performed directly in the solution of interest.
