Protein scaffolds from tobacco mosaic virus coat protein modified to incorporate polyhistidine can bind to a metal or a dye while having improved self-assembly characteristics. The scaffold can take the form of tubes or disks, and can further be formed into dual plasmonic ring resonators. Such self-assembled structures provide useful optical properties.

Metamaterial optical elements self-assembled on protein scaffolds

The present invention relates to compositions and methods for detecting analytes using detectably labeled fluorescent protein scaffolds. In certain embodiments of the invention, the scaffolds are viral particles in which the capsid viral structure provides a scaffold to attach detectably labeled fluorescent dyes and capture moieties that can be utilized to determine the presence of a desired analyte in a sample using any suitable method. The protein scaffold can contain amino acids carrying reactive groups (e.g., amines and thiols) that are spatially distributed on it with large enough separation to enable the attachment of a greater number of fluorescent label molecules without quenching.

Protein scaffolds and viral particles for detecting analytes

An electrically active particle is disclosed, having a virus scaffold. Nanoparticles are bonded to the surface of the virus, and the nanoparticles are connected to each other by, molecular wires.
