This article presents an overview of the recent progress made by our group in the development of bioelectrochemical imaging devices and systems with micro/nanoelectrodes. The topics include bioimaging of enzymes and live cells by scanning electrochemical microscopy (SECM), high-resolution bioimaging by SECM equipped with a nanoprobe, comprehensive measurements and bioimaging with local-redox cycling-based electrochemical (LRC-EC) devices, and rapid and sensitive bioimaging with BioLSI.
