The tip electrode generates a reactive species from a reversible redox mediator that diffuses to the substrate and reacts with an adsorbed. Surface-Interrogation Chronoamperometry Mode SECMĪ tip electrode is positioned in proximity to a substrate. This program models an extremely simple case of SECM in which a substrate electrode produces a substance of interest (e.g. A reversible mediator is reacted at the tip (described through concentration boundary conditions) and this mediator diffuses to the.Įlectrogenerated Chemiluminescence, ECL, involves the electrochemical generation of reactive species in solution, typically radical ions, which undergo highly exergonic reactions that are able to. This program models heterogeneous kinetics at a substrate. This is the simulation discussed in Koley D, Bard AJ (2010) Triton X-100 concentration effects on membrane permeability of a single HeLa cell by scanning electrochemical microscopy (SECM). With more than 30 components added to the software, you can use the. Using this software, you will be able to calculate the behavior of different or interconnected physical models. This program models a basic SECM configuration, using an ultramicroelectrode (UME) tip and a substrate with Butler-Volmer conditions for the electrochemistry of two redox pairs (o1/r1 at the tip and. COMSOL Multiphysics is a general-purpose software based on advanced numerical models for use in modeling and simulating physics-based problems.
