“…1,[15][16][17][18][19] We have used the infrared thermal diffusion forced Rayleigh scattering (IR-TDFRS) setup, 14 which slightly differs from the classical setup. The main difference is that no dye is needed for aqueous mixtures to convert the light energy into heat energy, due to the absorption of water at the wavelength of the infrared laser beam (λ w =980 nm).…”

We investigated the thermal diffusion phenomena of a rod-like mutant filamentous fd-Y21M virus in the isotropic phase, by means of an improved infrared thermal diffusion forced Rayleigh scattering (IR-TDFRS) set-up crucial for measurements of slowly diffusing systems.Since this is the first thermal diffusion study of a stiff anisotropic solute, we investigate the influence of the shape anisotropy on the thermal diffusion behavior. The influence of temperature, fd-Y21M concentration and ionic strength in relation with the thermodiffusion properties is discussed. We characterize and eliminate the effect of these parameters on the absolute diffusion of the rods and show that diffusion determines the behavior of the Soret coefficient because the thermal diffusion coefficient is constant in the investigate regime. Our results indicate that for the thermal diffusion behavior structural changes of the surrounding water are more important than structural changes between the charged macroions. In the investigated temperature and concentration range, the fd-Y21M virus is thermophobic for the low salt content, while the solutions with the high salt content change from thermophobic to thermophilic behavior with decreasing the temperature. A comparison with recent measurements of other charged soft and biological matter systems shows that the shape anisotropy of the fd-virus becomes not visible in the results.
