| Abstract
| - We have investigated the effect of the interfacial interaction on the cross-sectional morphology of the tobaccomosaic virus (TMV) in solution and on two types of solid substrates, SiOx (polar) on Si(100) and polystyrene film(nonpolar) on Si(100), using small-angle X-ray scattering (SAXS) and grazing incidence small-angle X-ray scattering(GISAXS), respectively. Results reveal that the flexible chains at the outer surface of TMV either expand or contractdepending on the nature of the substrate. Although the unfavorable interaction between the TMV and the PS causesa minimal effect, the stronger attractive interaction between the outer protein surface of TMV and the SiOx substrateinduces pronounced deformation of its cross-sectional morphology.
