abstract = "In this paper, we demonstrate a label-free ion-selective optical sensor for metal ion. This sensing mechanism is based on (1) selective formation of metal-ligand complex on the surface of nanoplasmonic probes and (2) selective plasmonic resonance energy transfer (PRET) between conjugated metal-ligand complex and gold nanoplasmonic probes (GNPs). We used functionalized GNP with ethylenediamine ligands in order to demonstrate high selectivity and sensitivity toward Cu2+. Due to the selective energy transfer from GNP to dd transition of the Cu2+ complex, the scattering spectrum of GNP changes quantitatively down to 1 nM of Cu2+.",
