   Abstract : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

4. 2. Localisation of Fluorescent Probes and the estimation of Lipid Nanodomain sizes by modern fluorescence techniques

   Author : Radek Sachl; Lennart B-Å Johansson; Martin Hof; Mats Almgren; Tomas Obsil; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic energy transfer; fluorescence; rafts; lipid bilayer; bicelles; micelles; fysikalisk kemi; Physical Chemistry;

   Abstract : The thesis is divided into two major parts. The first part focuses on the localisation of probes in lipid/polymeric bilayers and in GM1 micelles. Included in this thesis is a new approach based on electronic energy transfer/migration (FRET/DDEM), which efficiently determines transversal positions of fluorescent molecules in lipid bilayers.

6. 4. Phase Behavior and Solution Properties of Aqueous Polyion-Surfactant Ion Systems

   Author : John Janiak; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer-surfactant association; complex salt; nonionic surfactant; poly acrylic acid ; poly methacrylic acid ; copolymer; polymeric counterion; decyl betainate; phase behavior; solubilization; mixed micelle; hydrolysis; release; liquid crystal; nanoparticles; thermosresponsive; C12E8; C12E5;

   Abstract : Polyelectrolytes and oppositely charged surfactants interact through attractive electrostatic forces, which in many cases lead to phase separation already at low total concentrations. During the past 10-15 years investigations of these systems have been simplified through the use of complex salts that consist of surfactants with polymeric counterions in a 1:1 charge stoichiometry (no excess simple counterions present).

7. 5. Mixed Block Copolymer Solutions: Self-Assembly and Interactions

   Author : Solmaz Bayati; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer; Block Copolymer; PEO-PPO-PEO; Pluronics©; Bile Salt; NaGDC; PNIPAAM; PAMPTMA; PAMPS; Mixed Micelle; Self-Assembly; Mixed Complexes;

   Abstract : This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (PNIPAAM). Various techniques, such as dynamic and static light scattering (DLS and SLS), small angle X-ray and neutron scattering (SAXS and SANS), high sensitivity differential scanning calorimetry (HSDSC), turbidimetry, electrophoretic mobility measurements, and two-dimensional proton NMR nuclear Overhauser effect spectroscopy (2D 1H NMR NOESY), were applied to study these block copolymer systems.
