Effect of Mannosylerythritol lipid-A on light scattering of AOT/D2O/Octane

Resumo

The light scattering technique is used for the study of interaction of Mannosylerythritol lipid-A on AOT/D₂O/Octane. The collective diffusion of AOT/D₂O droplets soluble in Octane mixed with lipid is founded from a correlation function of light scattering. We focus on the variation of the dynamic behavior of droplets as a function of the lipid concentrations and the size of droplets. The increase of concentration of Mannosylerythritol lipid-A on microemulsion decreases the dynamic of droplets. The SAXS experiment shows the size and the interaction of the droplets change by increase of Mannosylerythritol lipid-A concentration. A hard sphere model can describe the interaction of lipid with AOT/D₂O droplets.
