Directed self -assembly of nanoparticles

Benjamin L Frankamp, University of Massachusetts Amherst


Nanotechnology promises to revolutionize the way we think about, but more importantly create new materials. The key to making this promise a reality is a commitment to fundamental research in critical areas including synthesis, fabrication, and characterization of nanoscale components. Nanoparticles have attracted wide attention as such components due to their unique size dependent properties including, superparamagnetism, chemilumiescents, and catalysis. To fully harness the potential capabilities of nanoparticles we need to develop new methods to assemble them into useful patterns or structures. Directed self-assembly using noncovalent interactions can be used to achieve this goal. This dissertation outlines experiments demonstrating several methods of polymer-mediated assembly of gold and iron oxide nanoparticles. Directed self-assembly using various polymer architectures provided a direct means to: (1) control the overall size of nanoparticle aggregates, (2) control interparticle spacing between particles, (3) control the collective behavior in nanoparticle ensembles.
