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. On the Formation of Supported Phospholipid Bilayers

   Author : Erik Reimhult; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; vesicle adsorption; formation kinetics; SPR; QCM-D; SPB; AFM; supported lipid bilayer; supported membrane; liposome;

   Abstract : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.

5. 3. Surface Modifications for Biointerfaces - Supported Lipid Bilayers and some Aspects of Microcontact Printing

   Author : Karin Glasmästar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QCM-D; PDMS; cell attachment; supported lipid bilayer; microcontact printing; SPR; ToF-SIMS; protein adsorption; formation kinetics; XPS;

   Abstract : Biointerfaces engage several disciplines: physics, materials science, chemistry, biology and medicine. They are found on the surfaces of implants, tubes and tanks in the food industry or on the hull of a boat. In this work, model surfaces aimed for contact with biological systems were studied.

6. 4. 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.

7. 5. 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
