  1. 1. Mesoporous supported lipid bilayers

    Författare :Maria Claesson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

    Sammanfattning : AbstractLipid bilayers are commonly used as simplified model systems of living cell membranes. They have shown to be important components in the development of biosensing devices where the bilayer acts as a host for transmembrane proteins, such as ion channels, that are utilized as sensing elements.

  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. On the Formation of Supported Phospholipid Bilayers

    Författare :Erik Reimhult; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vesicle adsorption; formation kinetics; SPR; QCM-D; SPB; AFM; supported lipid bilayer; supported membrane; liposome;

    Sammanfattning : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.

  5. 4. Biosensing and Protein Array Design using Lipid Assemblies

    Författare :Charlotte Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein adsorption; protein arrays; lipid bilayer; SPR; scFv; lipid vesicle; DNA arrays; QCM-D;

    Sammanfattning : Biomolecular sensing often includes immobilization of biomolecules, e.g. DNA, antibodies etc., to solid supports, where they act as selective recognition elements. LÄS MER

  7. 5. Interaction Between Antimicrobial Peptides and Phospholipid Membranes : Effects of Peptide Length and Composition

    Författare :Lovisa Ringstad; Martin Malmsten; Per Hansson; Jeremy Ramsden; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adsorption; antibacterial; antimicrobial peptide; bilayer; ellipsometry; electrochemistry; electrostatic interactions; hydrophobicity; liposome; membrane; monolayer; phospholipid; secondary structure; supported bilayer.; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Sammanfattning : Due to increasing problems with bacterial resistance development, there is a growing need for identifying new types of antibiotics. Antimicrobial peptides constitute an interesting group of substances for this purpose, since they are believed to act mainly by disrupting the bacterial membrane, which is a fast and non-specific mechanism.
