Scanning electrochemical microscopy in the 21st century. Update 1: five years after

Abstract

This Perspective is an update to our more extensive survey of scanning electrochemical microscopy (SECM) published in 2007. During this time, the SECM field retained its momentum by expanding into new areas and meeting the emerging scientific and technological challenges. Here we focus on most prominent developments such as high-resolution imaging, investigation of structures and processes on the nanoscale, alternative energy applications, and new approaches to solving “real world” problems. The fabrication of novel SECM probes and related theoretical advances are also discussed.
