The tutorial lecture will provide an overview of scanning electrochemical microscopy (SECM) and its prerequisites, limitations and fields of applications.

The main aspects will be:

• Scanning probe microscopy as a tool for gathering localized physical, topographic and electrochemical information.
• System set-up, imaging modes, achievable resolution. Combination with electrochemistry.
• Fabrication of micro- and nanoelectrodes and specific characteristics
• Feedback mode, generator collector mode, impedance and redox competition mode of SECM
• Application of SECM in biosensor development, material research, micro- and nanostructuring of surfaces, catalyst evaluation
