    • A classical experimental difficulty remains in the determination of the zero distance that could be difficult to determine with a good precision.8 To limit this problem in the comparison between the SECM approach curves, the solution containing the redox couple was changed with keeping the same positioning of the UME electrode in such way that all curves for a considered layer have a common origin

    • Another approach to address this issue would have been to use transient SECM as proposed by Unwin et al. ref 20b-d). Interest of transient SECM is to bring a more complete description of the system depending on time as steady state SECM provides a description at only one time. However, advantage of the second approach (as used here) is to be almost incentive to several possible artifacts as capacitance currents or ohmic drop

    • These values were measured by integration of the faradic peak in cyclic voltammetry7. It should be emphasized that the quantity of immobilized ferrocenes that is seen by the mediator from the solution side in the SECM conditions could be slightly different from what it is measured by classical electrochemical methods when the surface is used as a modified electrode
