Anti-fouling properties of an ionic liquid/poly(ionic liquid) gelled electrolyte for the electrochemical detection of bisphenol A

• A leakless IL/poly(IL) gel electrolyte was evaluated for BPA detection • The IL/poly(IL) gel prevents BPA oxidation fouling and electrode passivation • Mild electrode polarisation yields 100% current retention over five SWV scans • This protocol works on Pt thin-film, Pt macrodisk and glassy carbon electrodes A novel anti-fouling strategy has been developed to fully prevent electrode passivation caused by the polymeric by-products from bisphenol A (BPA) electrochemical oxidation.
