Self-diffusion of interacting micelles: FRAPP study of micelles self-diffusion

Abstract

We have studied self-diffusion in DTAB micellar systems at three different salinities with fluorescence photobleaching experiments. In order to characterize interactions in these systems, we have also performed light scattering experiments. Despite of the strong variation of the interactions with salinities, almost no salinity variation in self-diffusion coefficients vs droplets volume fraction curves has been observed. A clear difference between the friction coefficients involved in self- and mutual diffusion have been evidenced.
