A new fluorescent sensor based on the BODIPY fluorophore and the carboxyl-thiol metal bonding receptor for Hg-2(+) was designed and synthesized. The sensor is highly selective for Hg-2(+) (about 630-fold fluorescence enhancement) over relevant competing metal ions, sensitive to ppb levels of Hg2+ (with detection limit of 5.7 nM), and fast response toward Hg-2(+) (within 30 s) in aqueous solution.
