1. Sterically stabilised liposomes and related lipid aggregates : Fundamental studies on aggragate structure and stability
Sammanfattning : Various aspects of and approaches towards the steric stabilisation of liposomes have been investigated, mainly by use of fluorescence techniques and cryo-transmission electron microscopy (cryo-TEM). It is shown that PEG(2000)-lipids can be incorporated in the liposome membrane up to a critical concentration of 8-10 mol% without any observable structural perturbations. LÄS MER
2. Liposomes for Drug Delivery : from Physico-chemical Studies to Applications
Sammanfattning : Physico-chemical characterisation of structure and stability of liposomes intended for drug delivery is the central issue in this thesis. In addition, targeted liposomes to be used in boron neutron capture therapy (BNCT) were developed.Lysolipids and fatty acids are products formed upon hydrolysis of PC-lipids. LÄS MER
3. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation
Sammanfattning : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.

4. NMR Self-Diffusion Studies and Stability Studies of Emulsions
Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER
5. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms
Sammanfattning : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. LÄS MER
