摘要：

A sensor for Cu2+ ions is described based on modulation of the quenching of the photoluminescence of the perylene bisimide chromophore by gold nanoparticles (AuNPs, see Figure). The sensor turns on the fluorescence signal in the presence of Cu2+ ions-an advantage over traditional Cu2+ sensors, which turn off the signal-and shows specific recognition of Cu2+ over other metal ions.
