1. Protein-surfactant interactions
Abstract : 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. READ MORE

2. Association and Interactions in Protein-Surfactant Systems
Abstract : Aggregation in protein-surfactant systems have been studied with the ambition of reaching a deeper understanding of the balance of the interaction forces involved. A pure system with maximized electrostatic interactions has been used. READ MORE

3. Protein Nanomaterials: : Functionalization, Self-assembly, and Applications
Abstract : As one of the major classes of materials that is relevant to biological function of our daily life, proteins are highly interesting in both biological and material science. Self-assembled protein amyloid nanostructures have been considered not only as aggregates in pathological tissue, but also as a kind of advanced one dimension materials in material science perspective due to their favorable characteristics including high aspect ratio, abundant surface charge groups, high stability, and tunable surface properties.

4. Phase Phenomena in Polymer Networks : Empirical Studies on the Influence of Hydrophobicity, Charge Density and Crosslinks on Macroion-Induced Phase Transitions in Polyelectrolyte Gels
Abstract : The thesis concerns polyelectrolyte gels in contact with oppositely charged proteins and surfactant micelles, and includes of four papers (I-IV). In paper I confocal Raman spectroscopy was introduced as a method to trace micelles and investigate the structure of gel-surfactant complexes, in phase separated gel spheres. READ MORE

5. Self assembly of surfactants and polyelectrolytes in solution and at interfaces
Abstract : This thesis focuses on the study of the interactions between polyelectrolytes and surfactants in aqueous solutions and at interfaces, as well as on the structural changes these molecules undergo due to that interaction. Small–angle neutron scattering, dynamic, and static light scattering were the main techniques used to investigate the interactions in bulk. READ MORE
