Abstract

Free to be bright: Highly sensitive and convenient fluorescence turn-on detection of polyamines, important biomarkers for cancers, was achieved with a probe that consists of a cationic BODIPY adsorbed on gold nanoparticles (AuNPs), in which the fluorescence of the dye is completely quenched through efficient energy transfer, and is selectively recovered upon addition of the analyte (see figure).
