ExploreUnderstanding Scanning Electrochemical Microscopy
SECM is a powerful scanning probe technique that maps localized electrochemical activity. It works by positioning an ultramicroelectrode (UME) probe ↗ near a substrate surface in an electrolyte solution. The probe is polarized to drive a redox reaction of an electrochemical active species present in the solution. As the probe scans across the surface in the X-Y plane, the measured current reflects local variations in reactivity, conductivity, or topography.
One of the most common modes in SECM is the feedback mode. In this mode, the electrolyte contains a free-diffusing reversible redox mediator that undergoes electrochemical conversion at the SECM probe in a diffusion-controlled manner. As the probe approaches a conductive substrate, the mediator, oxidized or reduced at the polarized probe, is regenerated at the substrate and diffuses back to the probe, increasing the probe current (positive feedback). In contrast, when approaching an insulating substrate, the surface blocks the mediator diffusion to the probe, reducing the current (negative feedback).
Beyond amperometric feedback imaging, SECM systems support, among others, generation-collection mode, potentiometric imaging, and redox competition mode.
Spatial resolution in SECM is mainly governed by the size of the ultramicroelectrode probe and the probe-substrate distance. The active electrode diameter defines the lateral extent of the electrochemical measurement area, while the tip-substrate separation controls how much the diffusion layer spreads laterally before reaching the surface.
For high-resolution imaging, both a small probe diameter and close approach are required. Typical probe diameters range from tens of micrometers to a few hundred nanometers, enabling resolutions from micron down to nanometer scale. The RG value (the ratio of the overall glass insulator radius to the active electrode radius) also influences spatial resolution and probe behavior. Sensolytics probes provide the optimal balance for general SECM applications, ensuring a well-defined, predictable diffusion profile for the redox mediator while still allowing the probe to approach the surface closely without physical interference.
Sensolytics SECM systems are driven by integrated software ↗ that supports a comprehensive library of scan modes and measurement configurations without requiring time-consuming hardware reconfiguration:
