  1. 6. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

    Författare :Dorota Thid; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

    Sammanfattning : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.

  3. 7. Characterization of Membrane Proteins: From a gated plant aquaporin to animal ion channel receptors

    Författare :Sabeen Survery; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MIPs; AQPs; TRP ion channels; water transport; themo sensor; Electrophiles;

    Sammanfattning : Membrane proteins play several important roles in a cell. Among these proteins are aquaporins (AQPs) and transient receptor potential (TRP) ion channels that mediate water transport, temperature and noxious chemical sensation, respectively. LÄS MER

  4. 8. Structural Studies of Oligo(ethylene glycol)-Containing Assemblies on Gold

    Författare :Hung-Hsun Lee; Bo Liedberg; Magnus Johnsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : 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). LÄS MER

  5. 9. Controlling Chemistry and Membrane Proteome Composition in Nanotube-Vesicle Networks

    Författare :Brigitte Bauer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents a combination of experimental and theoretical techniques to elucidate the dynamics of chemical reactions in confined biological systems and bridges the gap between biomimetic and biological systems by using cell membranes as simplified biomimetic devices. These are in turn used and analyzed to draw conclusions about the cellular membrane makeup. LÄS MER

  7. 10. Partition chromatography of drugs on immobilized liposomes and biomembranes : A method applicable to screening in drug design

    Författare :Farideh Beigi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : One of the main pathways for drug passage into cells is diffusion across the lipid bilayer ofthe cell membrane. A key factor in this process is the drug partitioning into the bilayer, whichcan be translated into a retention in a chromatographic system. LÄS MER
