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.

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.
