Solution phase gold nanorings on a viral protein template.
Current studies on materials that exhibit metamaterial properties are mainly focused on lithography-generated 2D substrates. Here we report the successful fabrication of 22 nm gold nanoparticle rings with and without a central nanoparticle assembled on Tobacco Mosaic Virus coat protein disks. These structures are one of the first examples of nanorings produced independently of a substrate and represent the first steps toward the realization of a solution-phase or coatings-based metamaterial.
