1. 1. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

   Författare :Pauline Vandoolaeghe; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

   Sammanfattning : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. LÄS MER

3. 2. 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

4. 3. 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.

5. 4. Tethered Lipid Vesicles as Nanoscale Sensor Elements

   Författare :Seyed Tabaei; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aquaglyceroporin; lipid vesicles; total internal reflection fluorescence TIRF microscopy; cell membrane; aquaporin; pore formation; surface plasmon resonance SPR ; phospholipase A2; antiviral peptide; lipid bilayer; biosensing; microfluidics;

   Sammanfattning : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.
