Gold nanostructures aid the development of new photonic devices

Surface plasmon resonance—the collective vibration of electrons on the surface of metallic nanostructures in response to excitation with light or charge—has recently gained much attention from the scientific community because of its wide range of possible applications, particularly in photonics. Mohsen Rahmani and co-workers from the A*STAR Data Storage Institute have now expanded the potential uses of this phenomenon with their discovery that the surface plasmonics of assemblies of nanoparticles closely resembles the energetic interactions among atoms in two-dimensional molecules.
