Wang, University of South Carolina, demonstrates that biogenic assemblies can be further assembled in 1D manner which can be employed as template for the fabrication of waterdispersible, conductive polymeric nanowires. For instance, genetically modified viruses have already been proposed as templates for the assembly of nanometerscale components of electronic circuits see for instance Phonon Confinement Effects in Hybrid VirusInorganic Nanotubes for Nanoelectronic Applications. possible solution could lie in the use of selfassembled proteins, such as plant viruses, as nanotemplates for the synthesis of these nanowires.
So far, few studies have reported the use of selfassembled proteins, such as plant viruses, as nanotemplates for the synthesis of these nanowires. Researchers have successfully demonstrated the fabrication of waterdispersible, conductive PANi nanowiresusing the rodlike tobacco mosaic virus TMV as template.
They have also shown that much longer conductive PANiTMV nanowires >300 nm, greater than the length of native TMV particle can be formed by hierarchical assembly process. Using SSRM they measured the electronic properties of the composite nanofiber and calculated conductivity of 1 105 1cm1.

For instance, genetically modified viruses have already been developed.
The key concept behind our study of TMV templated polymeric nanowire is to take advantage of the selfassembly pathway of the TMV itself. Schematic demonstration of the conductive PANI nanowire synthesized by onsurface polymerization of aniline on TMV Image Dr. However, preparation of watersoluble, conductive PANi nanowires with controllable morphologies and sizes, especially with good processibility, is still big challenge.
