  3. 7. Unravelling the structure and dynamics of lipid nanoparticles for biomolecule delivery

    Författare :Jennifer Gilbert; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid nanoparticles; neutron scattering; SAXS; protein encapsulation; nucleic acid delivery; lipid self-assembly;

    Sammanfattning : Encapsulation in self-assembled lipid structures has been shown to increase the stability of large biomolecules, including proteins and nucleic acids (NAs), which has many potential applications in the food and pharmaceutical industries. In order to fully optimise the encapsulation system for a certain application, however, it is important to understand the effect of the encapsulated biomolecule on the lipid structure and vice versa.

  4. 8. Applications of Chromophores and Multiphoton Techniques to Study Structure and Interactions of Bio-macromolecules in Assembled State

    Författare :Piotr Hanczyc; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Z-scan; One-photon spectroscopy; oxazole yellow dyes; two-photon absorption.; non-linear spectroscopy; PVA DNA dyes films; linear dichroism; ruthenium complexes;

    Sammanfattning : The research presented in this thesis is concerned with the linear and nonlinear optical properties of biopolymers and the chromophores that bind to them. This thesis combines analyses of the interactions of biomolecules with technological improvements of already existing systems for bionanotechnology-related research. LÄS MER

  5. 9. Towards First-Principles Understanding of Biomolecular Adsorption

    Författare :Svetla Chakarova Käck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; phenol; adenine; graphite; biomolecules; van der Waals interactions; denaturation; protein; lattice models; PAH dimers; adsorption;

    Sammanfattning : A fundamental understanding of the interactions of biomolecules, such as proteins and DNA, with surfaces is of immense importance in numerous applications and poses a true challenge for theory. Density functional theory (DFT) is a quantum-mechanical tool well established for its ability to balance large system size with good accuracy in first-principles studies. LÄS MER

  7. 10. Conjugated polyelectrolytes : conformation sensitive optical probes for the recording of biological processes

    Författare :Peter Nilsson; Guillermo C. Bazan; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The physical properties of conjugated polymers can be utilized for a wide range of biosensors. For instance, the conformational flexibility fouud in conjugated polyelectrolytes, allows direct connection between the geometry of chains and the resulting electronic structure and optical processes, since the extension of the π-conjugated system is distorted by conformational changes of the polyelectrolyte backbone.
