Time-Resolved Fluorescence Microscopy Combined with Scanning Electrochemical Microscopy: A New Way to Visualize Photo-Induced Electron Transfer Quenching with an Electrofluorochromic Probe
Abstract:The combination of Scanning Electrochemical Microscopy (SECM) and Time-Resolved Fluorescence Microscopy was successfully implemented to investigate the control of the fluorescence of a tetrazine derivative in solution according to its redox state, a phenomenon called electrofluorochromism. The normalized fluorescence intensity difference between the 'on' and 'off' states can be tuned by the tip potential and the distance between the polarized tip and the substrate. It is demonstrated for the first time that lu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
