Description
Summary:Advancements in microelectrode fabrication, instrumentation, and theory have made data collection for scanning electrochemical microscopy (SECM) more accessible than ever before. In contrast, data treatment and analysis is still mostly done using proprietary or in-house tools or scripts. In this work, an open-source, free, Python-based software called Flux has been developed to treat SECM images, approach curves, cyclic voltammograms, and chronoamperograms. Flux provides a user-customizable data workflow that supports a range of common analyses including normalization of currents based on theoretical or experimental steady state currents, calculation of geometric (Rg), thermodynamic (formal potential), or kinetic (heterogeneous rate constant) parameters, and customizable plot formatting. Flux is compatible with standard output files from Biologic, CH Instruments, HEKA, and Sensolytics manufacturers.
