TL;DR: This work uses a combination of layer deposition techniques, including colloidal self-assembly, sputtering and atomic layer deposition, to fabricate photonic structures that mimic the colour mixing effect found on the wings of the Indonesian butterfly Papilio blumei and shows that a conceptual variation to the natural structure leads to enhanced optical properties.

TL;DR: Owing to the unique barrel-shaped geometry of CB[n] and their ability to bind "guest" molecules, the aggregates afford a new type of in situ self-calibrated and reliable SERS substrate where molecules can be selectively trapped by the CB[ n] and exposed to the nanojunction plasmonic field.

TL;DR: In this paper, the spectral dispersion of surface plasmon modes is analyzed for a set of different types of surface modes, such as delocalized Bragg and localized Mie plasmons.

TL;DR: Templated electrodeposition through colloidal templates is described to produce thin (<1 microm) films of palladium and platinum containing close packed hexagonal arrays of uniform sphere segment voids and it is shown that, even though these films are not rough, these surfaces give stable, reproducible surface enhancements for Raman scattering from molecules adsorbed at the metal surface.

TL;DR: In this paper, the authors compared boundary element calculations for the first time with experiment clearly and intuitively identifies plasmon wavefunctions in spherical voids according to their atomic-like symmetries.
