CFN Research Activities

We developed a solution-based method to synthesize palladium nanoparticle of different shapes, and investigated the relationship between nanoparticle shape, ligand shell, and the emergent phase behavior of nanocube assemblies using small-angle x-ray scattering and electron microscopy. We also developed a general strategy for DNA functionalization and mediated assembly of 3D ordered heterogeneous systems, comprising plasmonic (Au), magnetic (FeO, Fe2O3), catalytic (Pd), and luminescent (CdSe/Te@ZnS and CdS@ZnS QDs) NPs. This strategy provides tremendous opportunities to study the self-assembly behavior and collective properties of heterogeneous systems. We observed rich phase behavior and novel disorder-to-order transition pathway of the assemblies, and also investigated their properties, including photoluminescence and magnetic response.
