The central topic if this work was the comparative assessment of two analytical techniques: Pulsed Field Gradient Nuclear Magnetic Resonance (PFG-NMR) Spectroscopy and the Dynamic Nanosizing Microscopy (DNM). They are focused on the same physical parameter: the self diffusion, for determination of diffusion coefficients and particle sizes. With the methods introduced above nanocapsule dispersions are investigated with regard to their use in pharmaceutical applications. In this work especially the long time stability of dispersions, the dynamic of molecules like surfactants, oil and ethanol as well as the molecular exchange between the capsules and the environment were studied.
