Light-controlled imaging of biocatalytic reactions via scanning photoelectrochemical microscopy for multiplexed sensing

A light-controlled multiplexing platform has been developed on the basis of a quantum dot-sensitized inverse opal TiO electrode with integrated biocatalytic reactions. Spatially resolved illumination enables multiplexed sensing and imaging of enzymatic oxidation reactions at relatively negative appl...

Summary:A light-controlled multiplexing platform has been developed on the basis of a quantum dot-sensitized inverse opal TiO electrode with integrated biocatalytic reactions. Spatially resolved illumination enables multiplexed sensing and imaging of enzymatic oxidation reactions at relatively negative applied potentials.
