Templated self-assembly of sub-10 nm quantum dots
Patterned templates can guide the self-assembly of nanoparticles into ordered arrays. Our motivation in pursuing templated self-assembly is to develop a robust method for the creation of ordered structures at length scales below ten nanometers. The basic process entails creating surface relief …

Investigating the early events in proteasome assembly
… is the property of proteasomal subunits to self-assemble. While archaeal α and β subunits from Thermoplasma acidophilum can assemble into entire 20S units in vitro, certain α subunits from divergent species have a property to self-assemble into single and double heptameric rings. In this …

Self -Assembly Between Biomacromolecules and Lipids
Anionic DNA and cationic lipsomes can self-assemble into a multi-lamellar structure where two-dimensional (2-D) lipid sheets confine a periodic one-dimensional (1-D) lattice of parallel DNA chains, between which Cd2+ ions can condense, and be subsequently reacted with H 2S to template CdS nanorods …

Synthetic scaffolds and protein assemblies for engineering applications
S-layer proteins, which naturally self-assemble on the exterior of cells, provide an interesting basis for the creation of synthetic scaffolds. In this thesis, I created a plasmid which produces a recombinant form of a well characterized S layer protein, sbpA, which has a number of properties ideal …
