1. 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

2. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates
Abstract : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. READ MORE

3. Structural Adaptation of DNA to Small Ligands and Recombination Proteins
Abstract : In order to contribute to the understanding of mechanisms of recognition in nucleic acid systems, the interaction of DNA with a variety of ligands, representing different cases of adaptation of the double-helix structure, was studied using flow linear dichroism (LD), circular dichroism (CD), fluorescence and absorption spectroscopic techniques. A chiral hydrophobic metal complex, [Ru(dpphen)3]2+ was examined, since this had been reported to be the most efficient molecule to discriminate DNA handedness. READ MORE
