Abstract: One-dimensional ring structures from M13 viruses were constructed by two genetic modifications encoding binding peptides and synthesis of a heterobifunctional linker molecule. The bifunctional viruses displayed an anti-streptavidin peptide and hexahistidine (SEQ ID NO:4) peptide at opposite ends of the virus as pIII and pIX fusions. Stoichiometric addition of the streptavidin-NiNTA linker molecule led to the reversible formation of virus-based nanorings with circumferences corresponding to lengths of the packagable DNAs. These virus-based ring structures can be further engineered to nucleate inorganic materials and form metallic, magnetic, or semiconductor nanorings using trifunctionalized viruses.

Abstract: Eukaryotic cell display libraries for use in panning processes comprising expressed biomolecules for specific and selective binding and enrichment to solid material surfaces including, for example, metal, magnetic, and semiconducting surfaces. Display can be regulated. Peptide and protein display on yeast cells are preferred. Solid materials can be fabricated in the presence of cell display libraries which have been subjected to panning against the solid materials. Nanoparticles can be grown in the presence of the biomolecules from reactive precursors. The nanoparticles can show quantum confinement effects. Self-healing films can be prepared.
