1. Physico-Chemical Properties of Plant Polysaccharides Investigated with NMR Techniques
Sammanfattning : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. LÄS MER
2. NMR Studies of Colloidal Systems in and out of Equilibrium
Sammanfattning : The Thesis describes (i) the development of add-on instrumentation extending the capabilities of conventional NMR spectrometers and (ii) the application of the designed equipments and techniques for investigating various colloidal systems. The new equipments are: Novel designs of stopped-flow and temperature–jump inserts intended for conventional Bruker wide-bore superconductive magnets. LÄS MER
3. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels
Sammanfattning : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. LÄS MER
4. Studies of protein structure, dynamics and protein-ligand interactions using NMR spectroscopy
Sammanfattning : In the first part of the thesis, protein-ligand interactions were investigated using the chaperone LcrH, from Yersinia as target protein. The structure of a peptide encompassing the amphipathic domain (residue 278-300) of the protein YopD from Yersinia was determined by NMR in 40% TFE. LÄS MER
5. Solid-phase glycoconjugate synthesis : on-resin analysis with gel-phase ¹9F NMR spectroscopy
Sammanfattning : An efficient and versatile non-destructive method to analyze the progress of solid-phase glycoconjugate synthesis with gel-phase 19F NMR spectroscopy is described. The method relies on use of fluorinated linkers and building blocks carrying fluorinated protective groups. LÄS MER
