Extended Plasmonic Nanostructures Templated by Tobacco Mosaic Virus Coat Protein.

ABSTRACT: Optical and magnetic metamaterials possess interesting properties that cannot be achieved with conventional materials. However, there is currently no synthetic method offering both scalability and nanometer spatial precision. Biotemplating is a promising technique that has the potential to organize nanoscale components with high precision while being scalable and low-cost. Here, we demonstrate a versatile template using hexahistidine-tagged tobacco mosaic virus coat protein. The protein self-assembles into disks, which further assemble into extended nanostructures under mild conditions. Large sheets with either hexagonal or square packing and core-shell nanorods are formed, and gold nanoparticles are attached to the disks within each nanostructure to form assemblies of nanoparticle rings.
