Visualisation of electrochemical processes by coupled electrochemistry and fluorescence microscopy

The in situ coupling between electrochemistry and fluorescence microscopy is gaining popularity in the electrochemical community as a tool to image electrode processes in real time, providing useful spatial information which is not accessible by purely electrochemical methods. In recent years, new applications of electrochemical-fluorescence microscopy coupling have emerged, together with methodological developments that have expanded the possibilities of this technique. These recent trends are discussed in the present contribution, with an emphasis on the fluorogenic probes being employed.
