In this application note we describe how to carry out electrochemical AFM experiments in oxygen-free aqueous solutions employing FlexAFM and Electrochemistry Stage ECS 204 from Nanosurf
Ambient oxygen is known to readily dissolve in aqueous solutions and produce a reduction wave that interferes with many electrode reactions. Therefore, it is common to employ oxygen-free solutions for electrochemical experiments. In electrochemical SPM experiments, the deoxygenation represents a major technical challenge, and the studies are often limited to reactions which are not or only slightly affected by the presence of oxygen in solution.
