16. Tunable and modular assembly of polypeptides and polypeptide-hybrid biomaterials
Sammanfattning : Biomaterials are materials that are specifically designed to be in contact with biological systems and have for a long time been used in medicine. Examples of biomaterials range from sophisticated prostheses used for replacing outworn body parts to ordinary contact lenses. Currently it is possible to create biomaterials that can e.g. LÄS MER
17. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere
Sammanfattning : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.

18. Cellular Dyes and Bioactive Peptides - Cell Membrane Interactions and Cellular Uptake
Sammanfattning : Knowledge about mechanisms behind interactions of molecules with biomembranes and cellular uptake is very important for understanding biological processes and for drug design. The work described in this thesis has focused on interactions of cellular dyes and bioactive peptides with cells and the cell membrane. LÄS MER
19. The Role of Sugars for Protein Stabilization
Sammanfattning : The understanding of biomolecular interactions with water and co-solutes can lead to greater knowledge regarding the mechanisms behind biomolecular stabilization. This is highly important for developing technologies aimed to preserve biological materials. LÄS MER
20. DNA and RNA base analogue FRET - from fluorophore design to biochemical applications
Sammanfattning : This thesis focuses on the development and use of fluorescent base analogues (FBAs). They are important tools in research concerning nucleic acids structure, dynamics and interactions. LÄS MER
