Abstract: Recently there has been growing interest in the coupling of self-assembly chemistry with the formation of silver and gold nanoparticles, to create a new generation of materials of interest for sensing and optical devices. This talk describes the self-assembly modeling and optical properties of two classes of these materials: DNA-linked nanoparticle superlattices, and peptide amphiphile micelles and ribbons that incorporate nanoparticles. The presentation will focus on theoretical modeling, including the development of coarse-graining strategies for describing the assembly of DNA-linked superlattices, and peptide amphiphile fibers, and the use electrodynamics to describe the plasmonic properties of the metal nanoparticle structures. As one application we introduce a new approach to making alloys of plasmonic nanoparticles that have unusual metamaterials properties.
