  2. 1. Cubic Cell Membrane Architectures. Taking another look at membrane bound cell spaces

    Author : Tomas Landh; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; projections; image analysis; periodic cubic surfaces; membrane morphology; cubic membranes; cell ultrastructure;

    Abstract : A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations.

  4. 2. Electrochemical investigations on lipid cubic phases

    Author : Mohammad Yaser Khani Meynaq; Britta Lindholm-Sethson; Solomon Tesfalidet; Ehud M. Landau; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Abstract : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. READ MORE

  5. 3. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

    Author : Pauline Vandoolaeghe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

    Abstract : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. READ MORE

  6. 4. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

    Author : Lukas Boge; Martin Andersson; Lovisa Ringstad; RISE; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Liquid crystals; liquid crystalline nanoparticles; cubosome; hexosome; phase behavior; antimicrobial peptide; AMP; glycerol monooleate; proteolysis; antimicrobial effect; antimicrobial resistance; bacterial membrane; membrane interaction; infection; topical delivery; pulmonary delivery;

    Abstract : The development of antimicrobial resistance is a great challenge within health sectors worldwide. Thus, demand for new, efficient treatments is urgent in order to treat various bacterial infections. Antimicrobial peptides (AMPs) are a group of antibiotics that have gained more and more attraction in the past decade. READ MORE

  7. 5. Lipid sponge phase nanostructures as carriers for enzymes

    Author : Maria Valldeperas Badell; NanoLund: Centre for Nanoscience; []
    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.
