  1. 1. Equilibrium and Nonequilibrium Properties of Nonionic Surfactant Membranes

    Författare :Thao Le; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lamellar; multilamellar vesicle; small-angle x-ray scattering SAXS ; small-angle neutron scattering SANS ; static light scattering SLS ; joule heating temperature jump JHTJ ; dynamic light scattering DLS ; Nonionic surfactants; sponge; elastic curvature energy; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : An extensive investigation of the multilamellar vesicles (La*), lamellar (La), and multiply connected sponge (L3) phase formed in surfactant systems is presented in this thesis. These membrane structures were studied using surfactant systems containing poly(oxyethylene) alkyl ethers, n-CnH2n+1(OCH2CH2) mOH, commonly abbreviated as CnEm. LÄS MER

  3. 2. Membrane-Polymer Interactions in Lipid Vesicles

    Författare :Ilona Wegrzyn; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid nanotube; liposome; multifunctional pipette; PNIPAAm; lipid bilayer; giant unilamellar vesicle;

    Sammanfattning : Membrane related biological processes are commonly investigated in artificial biomimetic experimental systems. One of the most versatile models is based upon giant unilamellar phospholipid vesicles (liposomes), which are artificially generated spherical lipid structures in an aqueous environment. LÄS MER

  4. 3. Equilibrium and Kinetic Studies of the Binding of DNA to Cationic Liposomes

    Författare :Paula Barreleiro; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small-Angle Neutron Scattering; Fluorescence; Kinetics; Stopped-Flow; Differential Scanning Calorimetry; Titration Calorimetry; Gel-to-Liquid Crystalline Phase Transition; Lamellar phase; Lipolexes; DNA; Liposomes; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The objective of this work was to study the formation of DNA-cationic vesicle complexes (lipoplexes). These complexes are interesting not only from a fundamental point of view but also as promising candidates for gene therapy. The approach taken was to study first the cationic vesicles by themselves.

  5. 4. Advances in Soft Matter Nanofabrication

    Författare :Mehrnaz Shaali; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photolithography; negative e-beam resist; monolayer; confocal microscopy; Teflon AF; KPFM; DNA origami; cells; lipid nanotube; AFM; double bilayer; Phospholipid; electron beam lithography;

    Sammanfattning : The focus of this thesis is placed on the fabrication of engineered nanodevices for the manipulation of soft matter thin films. By combining top-down micro- and nanofabrication approaches with bottom-up self-assembly strategies, new research platforms were developed, tested and characterized. LÄS MER

  7. 5. Milk Membrane Lipids - Dispersions, Emulsions and Interactions with Proteins

    Författare :Rianne Waninge; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Model milk membrane lipids; Emulsions; Vesicles; Cryo-TEM; Milk fat globule membrane; MFGM; Livsmedelsteknik;

    Sammanfattning : Milk is a dilute aqueous dispersion with a complex mixture of proteins, fat, carbohydrates, vitamins and minerals. Milk membrane lipids are a part of the milk fat globule membrane (MFGM), which covers the fat globules. During dairy processing membrane material is released and surface structure features are altered. LÄS MER
