| 20080206838 | Nanoscaling ordering of hybrid materials using genetically engineered mesoscale virus - The present invention includes methods for producing nanocrystals of semiconductor material that have specific crystallographic features such as phase and alignment by using a self-assembling biological molecule that has been modified to possess an amino acid oligomer that is capable of specific binding to semi-conductor material. One form of the present invention is a method to construct ordered nanoparticles within the liquid crystal of the self-assembling biological molecule. | 08-28-2008 |
| 20080241531 | VIRAL FIBERS - Long rod shaped M13 viruses were used to fabricate one dimensional (1D) micro- and nanosized diameter fibers by mimic the spinning process of the silk spider. Liquid crystalline virus suspensions were extruded through the micrometer diameter capillary tubes in cross-linking solution (glutaraldehyde). Resulting fibers were tens of micrometers in diameter depending on the inner diameter of the capillary tip. AFM image verified that molecular long axis of the virus fibers were parallel to the fiber long axis. Although aqueous M13 virus suspension could not be spun by electrospinning, M13 viruses suspended in 1,1,1,3,3,3-hexafluoro-2-propanol were spun into fibers. After blending with highly water soluble polymer, polyvinyl 2-pyrolidone (PVP), M13 viruses was spun into continuous uniform virus blended PVP (virus-PVP) fibers. Resulting virus-PVP electrospun fibers showed intact infecting ability to bacterial hosts after suspending in the buffer solution. | 10-02-2008 |
| 20080242552 | MOLECULAR RECOGNITION OF MATERIALS - The present invention includes methods for selective binding of inorganic materials and the compositions that made up of the selecting agent and the target materials. One form of the present invention is a method for selecting crystal-binding peptides with binding specificity including the steps of contacting one or more amino acid oligomers with one or more single-crystals of a semiconductor material so that the oligomers may bind to the crystal and eluting the bound amino acid oligomers from the single-crystals. | 10-02-2008 |

One form of the present invention is a fabricated biofilm storage device with a biologic material applied to a substrate to form, e.g., a dry thin film stable at room temperature for extended periods of time. Another form of the present invention is a method of fabricating a biofilm storage device in which a biologic material is applied to a substrate under conditions that promote alignment of the biologic material on the substrate. The composition, method, and kit of the present invention have universal application in biologics, magnetics, optics and microelectronics. | 10-02-2008 |

| 20090269619 | Multifunctional biomaterials as scaffolds for electronic, optical, magnetic, semiconducting, and biotechnological applications - 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 packageable DNAs. These virus-based ring structures can be further engineered to nucleate inorganic materials and form metallic, magnetic, or semiconductor nanorings using trifunctionalized viruses. | 10-29-2009 |
