Using DNA to Design Plasmonic Metamaterials with Tunable Optical Properties

Authors


Abstract

Epsilon-near-zero behavior and an optically metallic response are predicted using electrodynamics simulations in superlattices comprising silver nanoparticles. Programmable DNA-mediated assembly is used to synthesize both silver and binary silver–gold nanoparticle superlattices, which are characterized using small-angle X-ray scattering, transmission electron microscopy, and elemental mapping.
