A turn-on fluorescent probe of propargyl-rhodol conjugate responds selectively to Au3+. In the presence of Au3+, the chemodosimeter undergoes a remarkable change in its absorption spectrum with a 370-fold fluorescence enhancement. This reaction-based Au3+chemodosimeter is highly sensitive with a detection limit of 7 ppb through an irreversible mechanism. Bioimaging of HeLa cells with this chemical probe has been successfully demonstrated.Mahidol UniversityChemical EngineeringChemistryArticleSCOPUS10.1039/c6ra02342h
