An electrochemical setup could be placed under the microscope in order to visualize and record the deposition process. A Leica DMRB microscope equipped with a 20x objective (Olympus LMPLFLN, 0.40 NA) and a Thorlabs C1284R13C camera was used. SEM characterization was undertaken with a FEI QUANTA 650 HRSEM with energy dispersive Xray spectroscopy (EDX Oxford Instruments INCA energy system). AFM images were undertaken in tapping mode with a Bruker Nanoscope dimension icon atomic force microscope. Electrochemical characterization of the substrates was undertaken using cyclic voltammetry as described above.
