  4. 22. Structural and Functional Studies of De Novo Designed Peptides at Surfaces

    Author : Patrik Nygren; Bo Liedberg; Thomas Ederth; Martin Malmsten; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biofouling; vesicles; nanoparticles; peptide; peptide design; circular dichroism; Physical chemistry; Fysikalisk kemi;

    Abstract : The work presented in this thesis deals with the structural and functional properties of peptides at surfaces. The interaction of peptides with surfaces is an ever so common occurrence in our every day life, from the bug squashed on the windshield of our car to the barnacle on our boat, and from the blood plasma used in the hospital to the proteins in our cells.

  5. 23. Lipid Vesicle Fusion: Investigation, Generation and Manipulation of Cell-Membrane Mimics

    Author : Lisa Simonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; spreading lipid bilayers; cell mimic; micromanipulation; lipid bilayer; microfluidics; site-specificity; DNA; membrane-receptor interactions; total internal reflection fluorescence microscopy; model system; self-assembly; TIRF microscopy; FRET; exocytosis; vesicles; fluorescence resonance energy transfer; biomembranes; amperometry; membrane fusion;

    Abstract : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. In this work, cell-membrane mimics were constructed and evaluated as models for studies of the membrane-fusion process. READ MORE

  6. 24. From single-molecule sensing to extracellular vesicles in glioma cells under stress

    Author : Virginia Claudio; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome; single molecule sensing; nanoplasmonics; surface plasmon resonance; exosomes; glioblastoma; extracellular vesicles; cellular stress; lipid composition;

    Abstract : This thesis describes the work I conducted in two different areas, namely biomolecular sensing and quantitative cell biology. The work in the former area was focused on the optimization of plasmonic metamaterials for sensing applications, and in the latter on the characterization of extracellular vesicles released by glioblastoma cells under stress conditions.

  7. 25. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing

    Author : Deborah Rupert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticle tracking analysis; exosomes; scattering; surface-based biosensing; optical density; cluster of differentiation 63 CD63 ; liposomes; label-free; fluorescence; surface plasmon resonance; Extracellular vesicles; specificity; antibody; lipid content; single particle; quantification; size distribution; optical waveguide microscopy;

    Abstract : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.
