Abstract

A new and facile assay for hydroxyl radicals in photocatalytic systems is reported for the first time that is based on the fluorescence imaging of increasing hydrophilic regions through the highly selective hydroxyl radical-induced lateral remote oxidation of superhydrophobic 1-octadecanethiol molecules at gold flower-like surface in the designed photomask setup.
