A colorimetric and fluorometric BODIPY probe for rapid, selective detection of H2S and its application in live cell imaging

Abstract

A BODIPY-azide based colorimetric and fluorescence turn-ON probe for rapid, selective and sensitive detection of H2S is reported. The probe displayed a fast response time (10 min in HEPES and 30 s in serum albumin), 28-fold fluorescence enhancement and low detection limit up to 259 nM. The application of the probe to the estimation of H2S in live cells was demonstrated.
