An extremely rapid-response fluorescent probe for hydrogen peroxide and its application in living cells†
Abstract
A turn-on fluorescence probe ACF for rapid detection of H2O2 was constructed. The probe utilized a 2-(azidomethyl)benzoyl group as a new reaction site, which exhibited a rapid response to H2O2 with a 118-fold fluorescence enhancement within 5 min. The biological application of ACF was confirmed by fluorescence imaging H2O2 in living cells.
