1. Synergies in Biolubrication
Sammanfattning : The objective of this thesis was to advance understanding in the field of biolubrication, finding inspiration from the human synovial joints. This was addressed by investigating the association of key biolubricants and the resulting lubrication performance. LÄS MER
2. Biolubricants and Biolubrication
Sammanfattning : The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants.

3. Biolubrication: Structural investigation of lubricin and its glycosylation
Sammanfattning : The sliding articular cartilage surfaces of the human diarthrodial joints are surrounded by biolubricating synovial fluid (SF), creating a perfect low friction biological biobearing structure with excellent lubrication and wear resistance, even during motion. Lubrication is predominately provided by surface adhered biomolecules including phospholipids, hyaluronic acid and synovial lubricin. LÄS MER
4. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles
Sammanfattning : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. LÄS MER
