Scanning electrochemical microscopy - a tutorial lecture

Wolfgang Schuhmann 

Ruhr-Universität Bochum, Anal. Chem. - Elektroanalytik & Sensorik (ELAN), Universitätsstr. 150, Bochum 44780, Germany

Abstract

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
