A Highly Selective Ratiometric Fluorescent Probe for Peroxynitrite Detection in Aqueous Media
Herein we developed a fast-responsive fluorescent probe 2-(benzo[d]thiazol-2-yl)-4-methylphenol (HMBT)-Py for ONOO- detection. HMBT-Py can react with ONOO- by an activated C=C oxidation cleavage reaction, causing a ratiometric change in the fluorescence spectra. In addition, HMBT-Py showed high selectivity to ONOO- over other reactive species.
