Abstract

Bis(picolinoyl)fluorescein, a new fluorogenic and chromogenic probe for monitoring the esterase activity of metal ions, has been synthesized. The probe is highly selective for Cu2+ and is applicable both to quantification of the free ion and detection of esterolytic activity of Cu bound to organic ligands or biomolecules, with a detection limit of 100 nM by fluorimetry.
