Interaction of gold nanoparticles with the protein shell of the tobacco mosaic virus is studied by x-ray photoelectron spectroscopy and spectrophotometry. As established, due to both the interaction of gold nanoparticles with the tobacco mosaic virus and the formation of complexes, a decrease in the binding energy of the Au4f core electrons by means of the Au\(^{3+}\)→Au\(^0\) metallization of nanoparticles is observed. Due to the sonication of complexes, in the Au4f spectra of the XPS, charge states appear, which indicate the formation of individual nanostructures from protein fragments of viruses and gold nanoparticles due to the destruction of the protein shell of viruses.

Keywords: x-ray photoelectron spectroscopy, gold nanoparticles, tobacco mosaic virus, sonication
