1. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization
Sammanfattning : 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. Membrane-Polymer Interactions in Lipid Vesicles
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
3. Transport Modes in Nanotube-Vesicle Networks
Sammanfattning : 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. LÄS MER
4. Nanotube Vesicle Networks: Immobilization and Transport Studies
Sammanfattning : 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. LÄS MER
5. Modification and Utilization of Nanotube-vesicle Networks
Sammanfattning : 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. LÄS MER
