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-mimetic systems : Novel methods and results from studies of respiratory enzymes

   Författare :Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

   Sammanfattning : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

4. 3. 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

5. 4. Lipid Vesicle Fusion: Investigation, Generation and Manipulation of Cell-Membrane Mimics

   Författare :Lisa Simonsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; spreading lipid bilayers; cell mimic; micromanipulation; lipid bilayer; microfluidics; site-specificity; DNA; membrane-receptor interactions; total internal reflection fluorescence microscopy; model system; self-assembly; TIRF microscopy; FRET; exocytosis; vesicles; fluorescence resonance energy transfer; biomembranes; amperometry; membrane fusion;

   Sammanfattning : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. In this work, cell-membrane mimics were constructed and evaluated as models for studies of the membrane-fusion process. LÄS MER

7. 5. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays

   Författare :Indriati Pfeiffer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA-array; cholesterol-DNA; EIS; membrane proteins; lipid vesicles; QCM-D; supported lipid bilayer;

   Sammanfattning : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.
