A ratiometric fluorescent hydrogen peroxide chemosensor manipulated by an ICT-activated FRET mechanism and its bioimaging application in living cells and zebrafish†
Abstract
A H2O2-responsive fluorescent chemosensor (CNBE) with a ratiometric emission signal was elaborately designed and synthesized. The ratio signal of the chemosensor was manipulated by an interplaying ICT-activated FRET mechanism. The ratiometric fluorescence imaging was successfully applied to detect H2O2 using CNBE in living cells and zebrafish.
