Integration of Electrochemistry and Optics
 |
JPK Instruments announced new electrochemical capabilities for their NanoWizard AFM systems. Electrochemical experiments study redox reactions of substances at a solid-liquid interface. With atomic force microscopy, high-resolution images can be obtained in liquid as the electrochemical reaction progresses. Electrochemistry spans a wide range of fields, from the corrosion of metal surfaces through to the role of protein electron transfer processes in biosensors.
The ECCell enables simultaneous AFM and electrochemistry with full environmental control. Uniquely, the cell enables simultaneous fluorescence experiments to be carried out when the NanoWizard AFM is operated on inverted optical microscopes. The key challenge for the electrochemical cell design is to integrate the many components and control elements within a small volume around the AFM tip. This has been successfully achieved with the ECCell, which offers the complete electrode set of working electrode, counter electrode and commercial reference electrode, together with an optional tip bias connection, for instance, for scanning electrochemical microscopy (SECM).
