  2. 26. Structure and Dynamics in Amphiphilic Bilayers: NMR and MD simulation Studies

    Author : Tiago Ferreira; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Solid-state nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) simulations were employed to study molecular structure and dynamics in amphiphilic bilayers. This thesis reports on method development and practical applications to two types of bilayer systems: simple cell membrane models composed of phosphatidylcholine lipids and cholesterol; and liquid crystals composed of ethyleneoxide-based surfactants often used in technological applications and in fundamental studies of amphiphile self-assembly.

  4. 27. Nanoparticle-based Capillary Electrochromatography - Separation of Small Molecules and Proteins

    Author : Christian Nilsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Capillary Electrochromatography; Green Fluorescent protein; Pseudostationary Phase; Capillary Electrophoresis;

    Abstract : The use of nanoparticle-based pseudostationary phases (PSPs) in capillary electrochromatography (CEC) for separation of small molecules and proteins is demonstrated. A continuous full filling approach is used where the nanoparticles are suspended in the electrolyte. READ MORE

  5. 28. Amyloid Proteins in Neurodegenerative Disease – Role of Extrinsic Modifiers

    Author : Nima Sasanian; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : ABSTRACT Self-assembly of disease-associated proteins into fibrillar homopolymers, so-called “amyloid fibrils” is a pathological hallmark of several debilitating human disorders, including Alzheimer’s disease (AD) and Parkinson’s disease (PD). AD and PD are associated with the formation of amyloid fibrils from the proteins amyloid-β (Aβ) and α-syn (α-syn), in the extracellular and intracellular space, respectively. READ MORE

  6. 29. Structural Studies of Oligo(ethylene glycol)-Containing Assemblies on Gold

    Author : Hung-Hsun Lee; Bo Liedberg; Magnus Johnsson; Linköpings universitet; []
    Keywords : ;

    Abstract : The work presents in this thesis has been focused on structural  characterization of a series of selected well-defined molecular architectures for the application as biomimetic membranes. The molecular architectures were prepared by self-assembly from dilute solution onto gold substrates, so called self-assembled monolayers (SAMs). READ MORE

  7. 30. Modification and Utilization of Nanotube-vesicle Networks

    Author : Martin Markström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; diffusion; network; nanotube; biomimetic; hydrogel; vesicle; compartmentalization; poly N-isopropyl acrylamide ; Marangoni; liposome;

    Abstract : Methods based on self-assembly and self-organization for construction of lipid bilayer networks, consisting of vesicles (3-100 μm in diameter) connected by conduits (50-300 nm in diameter), have previously been developed. Control over network geometry, topology, content, and membrane composition has been demonstrated. READ MORE
