Electrochemical scanning cell microscopy (SECCM) is a new pipette-based nanoelectrochemical scanning probe technique designed to study the local electrochemical properties of electrode surfaces using Park’s atomic force microscope. Using SECCM, researchers can perform thousands of confined nanoelectrochemical measurements (droplet area ranges from nm2 to µm2) on a single surface.
“My research included high resolution morphological test, precise positioning test and repeatability test to provide experimental evidence on routine and commercial application of SECCM,” General Liu comments. “Based on the described configuration, the clear information about the topographic and electrochemical activity of the self-assembly of ~45 nm gold nanoparticles was successfully recorded.”
As mentioned above, Park AFM’s very stable current control and extremely precise Z-head movement ensured smooth execution of accurate SECCM measurements. “Features include completely independent Z-direction displacement control as slow as 0.1 μm s-1 approach speed and low current detection capability less than 1.0 pA. All make possible the routinely operating SECCM to map the nanoscale surface chemical reaction in our research,” adds Liu.
