1. Controlled axonal outgrowth and cell reactions to nanostructures
Sammanfattning : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. LÄS MER
2. Quality and complications after cataract surgery
Sammanfattning : Research about IOL parameters` influence on posterior capsule opacification (PCO) and lens glistenings may be rapidly applied in clinical practice and may help the industry to manufacture intraocular lenses (IOLs) with higher quality, which will be of benefit to the patients. In paper I we compared the influence on PCO of 3 different IOLs; a sharp-edged hydrophobic acrylic, a round-edged silicone and a round-edged heparin-surface-modified polymethylmethacrylate (HSM-PMMA) IOL in a 5 year randomized prospective study with 180 patients.

3. Microfabrication for Biological Applications. Preparation, Characterization and Biological Evaluation
Sammanfattning : Foreign materials are intentionally placed into patients in the form of medical devices for replacing or repairing damaged portions of the body. Materials also enter the body unintentionally in the form of particulates and fibers, and can then have damaging effects, such as the formation of disease or even cancer. LÄS MER
4. Area Selective Chemical Vapor Deposition of Metallic Films using Plasma Electrons as Reducing Agents
Sammanfattning : Metallic films are used to improve optical, chemical, mechanical, magnetic, and electrical properties and are therefore of high importance in many applications, from electronics and catalysis, environmental protection and health, to wearable and flexible electronic materials. Many of these applications, however, require that the metal films are deposited uniformly on topographically complex surfaces and structures. LÄS MER
5. On the aetiology of aseptic loosening in joint arthroplasties, and routes to improved cemented fixation
Sammanfattning : Background: Aseptic loosening is the most common single cause for revisions in major joint arthroplasties worldwide. Different theories for aseptic loosening have been discussed during the last two decades. There is a need for improving fixation in both cemented and uncemented implants. LÄS MER
