| We have exploited lamellar polyelectrolyte multilayer heterostructures as sheet-like nanoreactors to synthesize silver nanoparticles with exquisite control over size, concentration and spatial location of the clusters in the layered structures. Metallodielectric photonic structures and bacterial resistant films have been studied. We have also applied our techniques to coat colloidal particles with layered films that contain nanoparticles; dissolving away the colloidal core leaves hollow microcapsules comprised of nanocomposite walls. Janus microparticles and microcapsules have also been produced. Along similar lines we have successfully patterned monolayers of block copolymer micelles on substrates; each micelle core provides a specified locus for inorganic cluster synthesis. In this way we have been able to create 2-D patterned arrays of catalyst particles for the synthesis of multiwall carbon nanotubes and zinc oxide nanowires. |
