1. 6. QCM-D – with focus on biosensing in biomolecular and cellular systems

   Författare :Erik Nilebäck; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; QCM-D; biomolecular interactions; cell-surface interaction; glycosaminoglycans; viscoelasticity; cell morphology; Quartz crystal microbalance with dissipation monitoring; surface chemistry; protein conformation;

   Sammanfattning : The high degree of complexity in biological systems is being investigated in greater and greater detail by increasingly sophisticated sensing approaches. The quartz crystal microbalance with dissipation monitoring (QCM-D) technique stands out in this context, by probing the viscoelastic properties at interfaces. LÄS MER

3. 7. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

   Författare :Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

   Sammanfattning :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. LÄS MER

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

   Författare :Seyed Tabaei; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 9. Modification of microcapsules for controlled release

   Författare :Markus Andersson Trojer; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; block copolymer; coordination chemistry; polyelectrolyte multilayer; cross-linking; vibrational spectroscopy; electron paramagnetic resonance; imidazole; controlled release; colloidal stability; Microcapsule; quartz crystal microbalance with dissipation;

   Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER

7. 10. Characterization of Surfaces Designed for Biomedical Applications

   Författare :Emma Kristensen; Hans Siegbahn; Rolf Larsson; Sven Oscarsson; Uppsala universitet; []
   Nyckelord :Physics; heparin; photoelectron spectroscopy; phosphorylcholine; biomaterial; quartz crystal dissipation; Fysik; fysik; Physics;

   Sammanfattning : In order to develop blood biocompatible materials a heparin surface and a phosphorylcholine (PC) functionalized polymer surface were characterized using photoelectron spectroscopy (PES). The formation of the heparin surface was studied by quartz crystal microbalance with dissipation monitoring (QCM-D). LÄS MER
