Scanning force microscopy combined with SECM

Finally, these capabilities have been scaled down to the imaging of manbranes with high density of nanopores thanks to the development of submicrometric probes and the combination of SECM with scanning force microscopy.

The quartz crystal nanobalance (QCN) can be combined with practically any electrochemical methods, such as cyclic voltammetry, chronoamperometry, chronocoulometry, potentiostatic, galvanostatic, rotating disc electrode [11], or potentiometric measurements. The EQCN can be further combined with other techniques, e.g., with UV-Vis spectroscopy [12], probe beam deflection (PBD) [13], radiotracer [14], atomic force microscopy (AEM) [15], and scanning electrochemical microscopy (SECM) [16]. The concept and the instrumentation of... 

A highly significant recent development is the integration of atomic force microscopy with SECM (AFM-SECM) [220]. Further details are described in Chapter 3.2 of this volume. An etched Pt wire was flattened and then insulated with electrophoretic paint. This probe acts as the cantilever in AFM and as the SECM tip providing dual force-sensing and electrochemical capabilities. Submicron resolution for SECM and for topography by AEM was achieved for test samples of track-etched polycarbonate membranes and ionic crystal surfaces. As the resolution of the technique improves and it is combined with other scanning probes, it seems likely that SECM can be applied in an ever-wider spectrum of scientific fields.
