  1. 11. The self-spreading double bilayer/Advances in lipid membrane nanotechnology

    Författare :Irep Gözen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; pore; lipid double bilayer; rupture; crackling noise; tension; self-spreading; vesicle; flat giant unilamellar vesicle; viscous fingering.;

    Sammanfattning : In my thesis I describe the generation, characterization and uses of self-spreading double bilayers. This new type of solid-supported model membrane combines features and properties of the 2D lipid bilayer membrane, and the 3D phospholiposome. The double bilayer membrane, i.e. LÄS MER

  3. 12. Grazing incidence small angle neutron scattering as a tool to study curved biomembranes on nanostructured surfaces

    Författare :Karolina Mothander; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GISANS; Reflectometry; Neutron scattering; Phospholipid; supported lipid bilayer; Nanowires; confocal microscopy; QCM-D;

    Sammanfattning : Curvature in lipid-based biomembranes provides compartmentalization in cells and can act as regulator of biological activity in living systems. The study of these biomembranes require novel model systems and new methods. In this work I have used a supported phospholipid bilayer on a hexagonal array of silicon nanowires. LÄS MER

  4. 13. Development and Evaluation of Preparation Methods for the Analysis of Cell Membranes Using Time-of-Flight Secondary Ion Mass Spectrometry

    Författare :Jakob Malm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; salt; cryofixation; TOF-SIMS; supported phospholipid bilayer; freeze drying; vacuum; cells; POPC; glutaraldehyde;

    Sammanfattning : The aim of this work was to evaluate and develop methods for preparing dry samples for TOF-SIMS analysis of cell membranes. For correct interpretation of the analysis data, an understanding of the effects that the preparation method has on the morphology and chemical structure of the sample must first be obtained.

  5. 14. 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.

  7. 15. Towards Energy-Efficient Drinking Water Production using Biomimicry

    Författare :Simon Isaksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filter; Membrane Protein; Supported Lipid Bilayer; Drinking Water; Water Treatment; Silica; Aquaporin; Liposome; Biomimicry;

    Sammanfattning : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration.
