title: Enhanced optical sensing of anions with amide-functionalized gold nanoparticles.
abstract: A gold nanoparticle surface-modified with amide ligands shows enhanced optical sensing of anions: the detection limit is increased by about three orders of magnitude higher than that originally expected from the anion binding ability of neutral amide ligands.
