DNA-Programmed Epitaxy of Nanoparticle Superlattices

Abstract

This AFOSR YIP will investigate methods to combine biomolecule directed self-assembly and lithographic patterning to generate nanoparticle-based materials with simultaneous and independent control over atomic composition, nanoscale structure, and macroscopic shape. These designer materials will consist of nanoparticle superlattices that are epitaxially grown in a layer-by-layer approach from a patterned substrate, using DNA-grafted nanoparticles as building blocks. The crystallographic arrangement of particles will be dictated as a function of DNA design, while the lattice size, shape, and orientation will be determined by the lithographically-patterned surface.
