Arranged into densely packed assemblies, noble metal nanoparticles display distinct optical properties that make these materials promising building blocks for mesoscopic waveguides, metamaterials or plasmonic sensors. This talk deals primarily with the bottom-up fabrication of regular 1D, 2D, and 3D assemblies of gold nanoparticles over macroscale areas by chemical and topographic structuring. Moreover, optical effects arising from the interplay of the near-field coupling and diffraction in periodic supercrystal arrays are discussed.
