1. Self aggregation of fluorocarbon surfactants and fluorocarbon- hydrocarbon surfactant mixtures
Sammanfattning : The aggregation and phase behavior of fluorocarbon surfactants in micellar, and liquid crystalline phases, and micellization in nonideal mixed fluorocarbon-hydrocarbon surfactant system have been investigated by means of a variety of techniques.The demixing in mixed surfactant systems was studied in the dilute solution region by using time-resolved fluorescence quenching measurements.

2. In vitro evaluation of formulations used in the treatment of hepatocellular carcinoma
Sammanfattning : Hepatocellular carcinoma (HCC) causes ~ 600,000 deaths annually, making it the second most deadly cancer form. HCC is classified into five stages and for the intermediate HCC treatment, the two most commonly used drug delivery systems (DDSs) are lipiodol-based emulsions and drug-eluting beads. LÄS MER
3. Association and Interactions in Protein-Surfactant Systems
Sammanfattning : 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. LÄS MER
4. Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules
Sammanfattning : A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

5. Organic Azides : Functional Molecules and Materials
Sammanfattning : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.
