The application staff of Park Systems will present an introduction to Scanning electrochemical cell microscopy (SECCM). SECCM is a nano-electrochemical scanning probe technique that creates a confined electrochemical cell (droplet) via meniscus contacting the surface by employing an electrolyte filled micropipette containing a quasi-reference counter electrode (QRCE). It allows researchers to investigate the local electrochemical properties of the electrode surfaces by directly mapping the electroactivity with nanoscale resolution. The electrochemically reversible [Ru (NH3)6]3+/2+ electron transfer process at a highly ordered pyrolytic graphite (HOPG) surface was recorded using the Park NX12 AFM system in this study.
Join us as the technical services engineer at Park Systems, explain the basics of SECCM and quantitative electroanalysis at the nanoscale using the Park NX12 AFM System.
