Electrochemical microscopy

The basic SECM device is quite simple and consists of four main elements:

• an electrochemical cell, including the UME probe, sample, reference electrode and counter-electrode (for simplicity, in some cases the reference electrode can also be used as a counter-electrode);

• a device for monitoring the relative positions of the UME and the substrate;

• a simple potentiostat or a bipotentiostat, if a potential is to be applied to the substrate;

• a data acquisition...
