Properties of nanowires based on the tobacco mosaic virus and gold nanoparticles

A study carried out of the physicochemical properties and the morphology of the nanowires based on the tobacco mosaic virus and gold nanoparticles obtained by atomic force microscopy and X-ray photoelectron spectroscopy. It was found that the nanowires prefer to cluster ordering. Its interaction with the substrate is characterized by C-N bond, while the bond N-C=O is characterized by binding virions with each other. The electronic Au 4fcore levels demonstrate shift towards lower binding energy at nanowires formation. It has been established that the obtained nanowires have optical activity with a maximum at 540 nm.
