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

    Author : Irep Gözen; Chalmers tekniska högskola; []
    Keywords : 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.;

    Abstract : 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. READ MORE

  4. 2. Membrane-Polymer Interactions in Lipid Vesicles

    Author : Ilona Wegrzyn; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipid nanotube; liposome; multifunctional pipette; PNIPAAm; lipid bilayer; giant unilamellar vesicle;

    Abstract : 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. READ MORE

  5. 3. Interactions of the Cell-Penetrating Peptide Penetratin with Model Membranes and Live Cells

    Author : Daniel Persson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antisense; antennapedia homeodomain; delivery vector; cell-penetrating peptide; protein transduction; uptake; membrane translocation; penetratin; confocal microscopy; vesicle;

    Abstract : The delivery of large, hydrophilic molecules, such as proteins and oligonucleotides, to the cytoplasm and nucleus of cells is problematic due to their generally low plasma membrane permeability. With the identification of a number of cell-penetrating peptides, capable of mediating non-endocytotic, intracellular delivery of macromolecular cargos, this obstacle now seems surmountable.

  6. 4. Interaction of Calcium Ions with Lipid Membranes

    Author : Baharan Ali Doosti; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Abstract : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

  7. 5. Advances in Soft Matter Nanofabrication

    Author : Mehrnaz Shaali; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photolithography; negative e-beam resist; monolayer; confocal microscopy; Teflon AF; KPFM; DNA origami; cells; lipid nanotube; AFM; double bilayer; Phospholipid; electron beam lithography;

    Abstract : The focus of this thesis is placed on the fabrication of engineered nanodevices for the manipulation of soft matter thin films. By combining top-down micro- and nanofabrication approaches with bottom-up self-assembly strategies, new research platforms were developed, tested and characterized. READ MORE
