2. 1. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes

   Author : Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

   Abstract : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

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. New directions in non-porous membrane extraction

   Author : Eddie Thordarson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; extracting syringe; solvent-free; miniaturisation; micro-porous membrane liquid-liquid extraction; polymeric membrane extraction; Non-porous membrane extraction; supported liquid extraction; integration; automation; Analytical chemistry; Analytisk kemi;

   Abstract : Complex biological and environmental samples require a high degree of selectivity in order to determine components therein. Sensitivity measures, such as analyte pre-concentration are often required for assessing composition quantitatively. READ MORE

6. 4. Development of Surface-Based Methods for Studies of Non-Electrolyte Membrane Transport

   Author : Seyed Tabaei; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane junction; surface plasmon resonance; membrane transfer; supported lipid bilayer; quartz crystal microbalance; aquaporin; bicelles; fluorescence microscopy;

   Abstract : Membrane-transport proteins are a diverse family of proteins that all span the cell membrane where they control the transfer of nutrients, metabolites and ions into and out of the cell. Due to their vital role for the function of cells, reliable methods, preferably with high-throughput capacity, to study this class of proteins are essential in fundamental studies as well as in discovery and development of new drugs.

7. 5. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

   Author : Dorota Thid; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

   Abstract : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.
