The article presents an approach for determination of low activity hydrolases down to the nanoscale amount. It consists in a specific design of fluorescent indicator using Excited-State Intramolecular Proton-Transfer (ESIPT) phenomenon and enhancement of its fluorescence on the metal surface (Metal Enhanced Fluorescence - MEF). The developed approach is tested with beta-glucosidase using novel ESIPT fluorescent indicator from the flavonol family.
