11. Interaction Between Microgels and Oppositely Charged Peptides
Sammanfattning : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. LÄS MER
12. Microgels as Carriers for Antimicrobial Peptides : Surface-bound microgels, and factors affecting peptide interactions
Sammanfattning : With a growing number of multi-resistant bacteria against conventional antibiotics, there is an urgent need to identify new antimicrobial therapeutics. One example that has gained considerable interest is antimicrobial peptides (AMPs). LÄS MER
13. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging
Sammanfattning : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. LÄS MER
14. A microfluidic toolbox to fabricate, sort and characterize thermoresponsive colloidal molecules and their assemblies
Sammanfattning : In this thesis we discuss the assembly of thermoresponsive microgel particles into small clusters, and their use as colloidal molecules with specific and directional interactions. The underlying goal is to use these particles as advanced building blocks for new types of self- assembled structures with novel or vastly improved properties, and as model particles for investigating fundamental problems in condensed matter physics.

15. Surface nanomechanical properties of hydrogels and coatings
Sammanfattning : Characterizing mechanical and wear properties at the nanometer scale emerged as a fascinating and challenging topic in the last decades due to recognition of many interesting and unusual properties of nanomaterials. Due to recent developments of the atomic force microscopy (AFM) technique, it is now possible to measure nanomechanical properties and topography simultaneously, as well as performing and evaluating wear measurements at the nanometer scale.
