  1. Viruses Fall into Line: Synthesis of Composite Nanofibers by Controlled Self-assembly of Tobacco Mosaic Virus Qian Wang, University of South Carolina, DMR-0706431 A versatile assembly process has been developed to prepare water-soluble conductive polyaniline(PANi)/virus composite nanowires using tobacco mosaic virus (TMV) as template. Highly negative-charged poly(sulfonated styrene) (PSS) was used both as a dopant acid and a stabilizing agent to improve the stability of the composite fibers in aqueous solution. The resulted fibers are highly conductive. • Chem. Commun.2006, 3019-3021. • NanoBiotechnology, 2007, 3, 31-39. • Langmuir2007, 23, 6719-6724. • J. Biomedical Mater. Res.

Viruses Fall into Line: Synthesis of Composite Nanofibers by Controlled Self-assembly of Tobacco Mosaic Virus Qian Wang, University of South Carolina, DMR-0706431 Bacteriophage M13 can also be used as template to produce conductive nanofibers. The fibers can be easily fabricated into thin conductive films due to the high aspect ratio and good solubility in aqueous solution. This synthesis discloses a unique and versatile way of using bionanorods to produce composite fibrillar materials with narrow dispersity, high aspect ratio and high processibility, which may have many potential applications in electronics, optics, sensing and biomedical engineering.
