Fig. 15. Scheme of the SI-SECM setup and the feedback response (on the right) representing the substrate detection of the analyte generated at the tip (FcDM+ reduction at the tip). The tip current is expressed in black and substrate current in red. The concentrations of FcDM and IrCl62− were 1.2 and 1.1 mM respectively.
