Cyclic voltammetry of UCDEs vs. Ag/AgCl (1 M KCl) in PBS (pH 7.4) with 5 mM K3Fe(CN)6 a before and b after electrochemical cleaning in H2SO4. c EIS performance in PBS (pH 7.4) with 5 mM K3Fe(CN)6. Cyclic voltammetry performance of UCDEs as a Ag/AgCl reference electrode vs commercial Ag/AgCl (1 M KCl) electrode with d 1 M and e 0.01 M Cl−. f Calibration curve of the UCDE reference electrode compared to a commercial Ag/AgCl (1 M KCl) electrode. g Potentiometric performance of the UCDE as a pH sensor (vs. fabricated Ag/AgCl UCDEs reference electrode). Inset is the associated calibration curve of the pH sensor. Amperometric performance of the UCDEs as a h oxygen, i glucose, and j lactate sensor (vs. fabricated Ag/AgCl UCDEs reference electrode). Insets are the corresponding calibration curves.
