Abstract
Disclosed is an innovative method for detecting metal ions based on selective plasmonic resonance energy transfer between metal-ligand complexes and a single nanoplasmonic particle as a probe. The selective plasmonic resonance energy transfer occurs if a resonance frequency matching condition between the single nanoplasmonic particle and the metal-ligand complexes is satisfied.
