A Reducing and Oxidizing System Minimizes Photobleaching and Blinking of Fluorescent Dyes

Abstract

On the ROXS: Photobleaching represents one of the main limitations of modern fluorescence microscopy. A reducing and oxidizing system (ROXS) has been introduced that recovers triplet states as well as charge-separated states through electron-transfer reactions (see picture). Thus the blinking and photobleaching of fluorophores is strikingly reduced.
