    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Imberg; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Biodegradable; CLSM; Composite Particles; Controlled Release; Cubic Phases; Drug Delivery; Flory-Huggins Theory; FT-PGSE-NMR; IPMS; Liquid Phase; Lipid Domains; Liquid Handler; Microspheres; Microstructure; Phase Behaviour; Phase Separation; Polymer Matrix; SAXS; Segregation; Sponge Phase; Swelling; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

    Abstract : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. READ MORE

  2. 2. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains

    University dissertation from Food Technology, Lund University

    Author : Katarina Ekelund; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatty acids; Langmuir-Blodgett films; AFM; domains; stratum corneum; bilayer curvature; lipids; glycerol monooleate; phase behaviour; sponge phase; L3 phase; Livsmedelsteknik; cholesterol; Food and drink technology;

    Abstract : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. READ MORE

  3. 3. Lipid sponge phase nanostructures as carriers for enzymes

    University dissertation from Lund University, Faculty of Science, Department of Chemistry

    Author : Maria Valldeperas Badell; [2019-02]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sponge phase; lipid liquid crystals; DGMO; GMO-50; polysorbate 80; encapsulation of proteins; Aspartic protease; β-galactosidase; X-ray and neutron scattering; Raman spectroscopy; adsorption; cryo-TEM;

    Abstract : Nonlamellar lipid liquid crystalline phases have many potential applications, such as for drug delivery, protein encapsulation or crystallization. Lipid liquid crystalline sponge phase (L3) has so far not been very much considered in these applications, in spite of apparent advantages in terms of its flexibility and capacity of forming large aqueous pores able to encapsulate large bioactive molecules.

  4. 4. On the crystallization of membrane proteins in lipidic sponge and cubic phases

    University dissertation from Lund University, Faculty of Science, Department of Chemistry

    Author : Pia Jeanette Hindrichsen; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

    Abstract : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. READ MORE
