The scanning vibration electrode technique (SVET), providing a map of the current density, allows demonstration of the termination of the corrosion process under irradiation. Fig. 2a shows the corrosion current map recorded after 36 h of immersion of the SiOx ZrOx film with IR-laser light sensitive BSA-loaded nanocontainers Ti02 Ag/PEI/PSS/PEI/PSS. Before immersion, the film was... 

Recently, two new electrochemical mapping techniques have become available the scanning vibrating electrode technique (SVET) and the localized electrochemical impedance spectroscopy (LEIS) technique. These techniques provide the capability to identify and monitor electrochemical behavior down to the micron level. These represent significant advances over traditional electrochemical methods (cyclic voltammetry, EIS, and even EQCM), which provide data that reflect only an average over the entire sample surface. Although such data are very useful, a major drawback is that no local or spatial information is obtained. 

The scanning vibrating electrode technique (SVET) uses a microelectrode capable of measuring potential gradients in the corrosion solution near localized corrosion. It locates and measures corrosion at specific points of the corroding surface [9]. This technique performs in situ locahzed corrosion measurements occurring on the surface. During the measurement, the microelectrode vibrates perpendicular to the surface. The tip of the...
