Within our GRK on confinement-controlled chemistry we attempt to understand how a confinement by reverse micelles controls chemical reactions. These assemblies of nanoscale water pools solubilized by a layer of surfactants in nonpolar solvents find application in many areas of science and technology. For instance, they can be employed as chemical and enzymatic nanoreactors1, in nanoparticle synthesis 2 or as experimental models for physically confined systems with limited amounts of water3. Understanding the composition, size and morphology of micellar structures can improve the applications further. We study these systems by scattering techniques such as dynamic light scattering (DLS), small angle scattering (SAXS), UV-Vis, and FTIR spectroscopy.
