Abstract:
1. A method for detecting metal ions, comprising: investigating whether plasmonic resonance energy transfer occurs between a single nanoplasmonic particle and metal-ligand complexes where the targeted metal ions are coordinated with ligands to form the metal-ligand complexes, wherein the metal ions are Cu 2+ , and the ligands are at least one selected from the group consisting of N-[3-(trimethoxysilyl)propyl]ethylenediamine (TMSen), 6-aminohexane thiolhydrochloride (AHT), 2-aminoethane thiolhydrochloride (AET), NH 2 -Gly-Gly-His-COOH and NH 2 -(His)6-COOH.
