2. 1. Mesoporous supported lipid bilayers

   Author : Maria Claesson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

   Abstract : 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.

4. 2. Formation of Mesoporous Materials and their use as Lipid Bilayer Supports

   Author : Maria Wallin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tethered lipid bilayers; meso-ordered PEG-DA hydrogels; dendrimers; porous silica and titania; lipid bilayers; biosensing;

   Abstract : Mesoporous materials have acquired great scientific interest in various applications; something that is largely due to that their properties, such as pore size, pore orientation, material composition and surface chemistry, can be controlled to a large extent. One idea, which has been investigated in this thesis, is to use mesoporous materials as supports for lipid bilayers and by doing so fabricate devices that mimic the cell wall and at the same time has sufficient mechanical robustness for practical use.

5. 3. Tethered Lipid Vesicles as Nanoscale Sensor Elements

   Author : Seyed Tabaei; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.

6. 4. Supported Lipid Membranes and Their Use for the Characterization of Biological Nanoparticles

   Author : Silver Jõemetsa; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; supported lipid bilayer; lipophilic dyes; size determination; diffusion; microfluidics;

   Abstract : Biological nanoparticles (BNPs) are nano-sized lipid vesicles of biological origin, which are involved in multiple biological processes. BNP characterization techniques are critical for improving the understanding of how these particles contribute to cellular communication, viral infections and drug-delivery applications. READ MORE

7. 5. Self-assembly Strategies for Functional DNA Nanostructures

   Author : John Tumpane; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; polarised spectroscopy; nanotechnology; self-assembly; orientation; lipid membrane; gel electrophoresis; DNA;

   Abstract : The technological revolution of the twentieth century was famously subject to Moore’s law which related the rate of growth to the ability to scale-down the size of the components – size matters. Several decades later we are, however, approaching the limit of what is possible with silicon wafers. READ MORE
