Selectivity test of Nafion-coated graphene. a HCl, b KCl, and c NaCl solutions were tested with identical concentrations of 1–5 mM. d Glucose, e uric acid, and f ascorbic acid solutions were also tested to define the selectivity of Nafion-coated graphene. Response results to pH (8.05), glucose (5 mM), uric acid (5 mM), and ascorbic acid (5 mM) of g pristine graphene, h Nafion-coated graphene, and i Au-decorated graphene.
