Abstract

Scanning electrochemical microscopy (SECM) is a technique that employs a microelectrode as a tip to get electrochemical information with high spatial resolution. The current measured at the tip corresponds to electrochemical processes taking place in a micrometric region surrounding the tip and a specific substrate. SECM has been used to characterize and image various electrochemical systems such as polymers, nanomaterials, electrode surfaces, and liquid–liquid interfaces. Owing to new technologies to fabricate tips in the nanometer dimension (nanoelectrodes), SECM has evolved as a fundamental tool for investigating molecular-level chemical reactions in biological systems. Herein, we shall give an overview of the applications of the technique in multidisciplinary areas ranging from biological research to materials science, energy-related topics, catalysis, and corrosion.
