Event Details & 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, 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.
