1. Vesicle - surfactant interactions : effect of non-ionic surfactants on structure and leakage of small unilamellar vesicles
Sammanfattning : .... LÄS MER
2. Protein-surfactant interactions
Sammanfattning : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. LÄS MER
3. Catanionic Surfactant Mixtures and Binary Systems of Modified Fatty Acid Surfactants. Phase Equilibria and Structure
Sammanfattning : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

4. Environmentally Responsive Surface Coatings of Polyion-Surfactant Ion Complex Salts
Sammanfattning : Complexes formed between oppositely charged polyions and surfactant ions are known to have very rich phase behaviour in bulk solution. The work in this thesis investigates the possibilites of using such complexes as surface coatings. LÄS MER
5. Characterisation of Aqueous Solutions, Liquid Crystals and Solid State of Non-ionic Polymers in Association with Amphiphiles and Drugs
Sammanfattning : Cellulose ethers and polyethylene glycols are used in drug formulations as water swelling or water soluble matrices. Polar lipids, for example monoglycerides, and surfactants can be used to solubilise hydrophobic or amphiphilic drugs and to formulate potential drug delivery vehicles such as emulsions, liposomes and cubic phases.
