By a reusable transfer fabrication technique, we demonstrate high‐fidelity fabrication of metal nanoparticles, optical nanoantennas, and nanohole arrays directly on a functional silk biopolymer. The ability to reproducibly pattern silk biopolymers with arbitrarily complex plasmonic arrays is of importance for a variety of applications in optical biosensing, tissue engineering, cell biology, and the...
We design and demonstrate angle-insensitive structural color by engineering plasmonenhanced light scattering from homogenized Pinwheel arrays of Au nanoparticles on Au substrate for plasmonic applications, like displays, security tagging and solar cells.
A golden-angle spiral lattice can posses an omnidirectional photonic bandgap despite the lack of translational and rotational symmetries. We show that the band edge modes are spatially localized and possess discrete angular momenta.
