title: Tunable surface-enhanced Raman scattering from large gold nanoparticle arrays.
abstract: Raman signal enhancements in excess of 10(7) can be achieved at near-infrared wavelengths when mid-nanometer sized gold particles self-organize into close-packed planar arrays. These substrates generate stable surface-enhanced Raman scattering which changes dramatically as a function of periodic structure and excitation wavelength.
