  1. 1. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization

    Author : Tatsiana Lobovkina; Chalmers University of Technology; []
    Keywords : circular nanotube; shape transition; enzymatic reaction; nanotube knot; self-organization; liposome; lipid nanotube; lipid vesicle; nanotube-vesicle network;

    Abstract : Nanotube-vesicle networks (NVNs) are simplified models of cell membrane tubular systems which are dynamic transportation routs for molecular cargoes in biological cells. The presented work describes dynamic properties of NVNs such as self-organization, shape and topology transformations; moreover, specific geometric properties of the networks are used for controlling enzymatic reactions.

  2. 2. Membrane-Polymer Interactions in Lipid Vesicles

    Author : Ilona Wegrzyn; Chalmers University of Technology; []
    Keywords : 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

  3. 3. Transport Modes in Nanotube-Vesicle Networks

    Author : Michal Tokarz; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; confinement; liposome; biomimetic; micromanipulation; Vesicle; electrophoresis; network; nanotube; transport;

    Abstract : Methods for construction of surface-immobilized microscopic networks of phospholipid bilayer vesicles (3-50 µm in diameter) interconnected by lipid tubes (30-150 nm in radius), have previously been developed. The networks have controlled connectivity and are well-defined with regard to container size, content, angle between nanotube extensions, and nanotube length. READ MORE

  4. 4. Nanotube Vesicle Networks: Immobilization and Transport Studies

    Author : Johan Hurtig; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; network; electrophoresis; nanotechnology; liposome; biomimetic; confocal microscopy; Vesicle; microfabrication; nanotube;

    Abstract : Surfactant lipids are an essential element of living cells. They are the basis for the biomembranes that envelope and divide cells into compartments. In addition to this static function, lipid membranes also play a role in dynamic processes such as transport and signaling. READ MORE

  5. 5. Modification and Utilization of Nanotube-vesicle Networks

    Author : Martin Markström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; diffusion; network; nanotube; biomimetic; hydrogel; vesicle; compartmentalization; poly N-isopropyl acrylamide ; Marangoni; liposome;

    Abstract : Methods based on self-assembly and self-organization for construction of lipid bilayer networks, consisting of vesicles (3-100 μm in diameter) connected by conduits (50-300 nm in diameter), have previously been developed. Control over network geometry, topology, content, and membrane composition has been demonstrated. READ MORE
