Scanning Electrochemical Microscope (SECM)

The Scanning Electrochemical Microscope (SECM) consists of a digital function generator, a bipotentiostat, a three dimensional nanopositioner, high resolution data acquisition circuitry, and cell holder. The principle of SECM is based on the movement of the microelectrode over the conductive or insulating surface. SECM can image chemical or biochemical activities present at a surface.
