In complex colloidal systems, particle-poor regions can develop within particle-rich phases during sedimentation or creaming. These particle-poor regions are overlooked by 1D profiles, which are typically used to assess particle distributions in a sa

In order to study the sedimentation of pharmaceutical suspensions using low-field one dimensional pulsed field gradient nuclear magnetic resonance (1D pfg NMR) profilometry, the accuracy of signal acquisition as well as the spatial resolution of a co

Polysorbate surfactants (commercially available as Tween) are widely used in pharmaceutical, cosmetic and food products. They are generally considered as esters of ethoxylated sorbitan with fatty acids. Diffusion H1 NMR spectroscopy on a solution of

The influence of the physicochemical properties of the vesicular bilayer on the sorption of poorly water soluble compounds was investigated with pulsed field gradient 1H nuclear magnetic resonance (PFG-NMR) for the case of phosphatidylcholine and dio

The change in particle size distribution of casein micellar dispersions induced by heating both in the absence and presence of whey proteins was investigated by two techniques. Whereas dynamic light scattering (DLS) is an ensemble technique that trie

Magnetoliposomes (MLs) consist of nanometre-sized magnetite cores, enwrapped by a bilayer of phospholipid molecules. In the past we showed that these nanocolloids can be exploited as powerful biocompatible magnetic resonance imaging (MRI) contrast ag

Dispersions of multilamellar dioctadecyldimethylammonium chloride (DODAC) vesicles are known to have a wide range of sizes and lamellarities. Osmotic effects on these dispersions were investigated by means of NMR diffusometry and small angle X-ray sc

The interaction mechanism of cationic diethylester dimethylammonium chloride (DEEDMAC) vesicles and the anionic surfactant sodium dodecyl sulphate (SDS) was investigated. Electrophoretic mobility measurements showed that the outer monolayer of the DE

Extruded vesicles, which are often used as models for living cells, can change their morphology when they are diluted into a hyperosmotic medium. Different morphological changes were observed with extruded dioctadecyldimethylammonium chloride (DODAC)

The enclosed volume of concentrated dioctadecyldimethylammonium chloride (DODAC) dispersions has been determined by means of low-resolution NMR pfg-diffusometry and T-2 relaxometry. The pfg-NMR diffusometry method is based on the different diffusion
