Abstract
A shear force-based ion-selective probe for scanning electrochemical microscopy was fabricated for the imaging of localized potassium ions. A solution of dibenzo-18-crown-6/1,2-dichloroethane was added to a pulled capillary which was contact with a tuning fork attached to a piezoelectric buzzer. 10 μm of a Nafion island on glass was imaged, and the topography and current image originating from localized potassium ion concentration were obtained.
