摘要：

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. © 2013 WILEY-VCH Verlag GmbH & Co.
