2. 1. Protein and Cell Interactions with Nanostructured Surfaces

   Author : Emma Westas; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; titanium dioxide; implant associated infections; metabolomics; cellular interactions; hydroxyapatite; immune complement activation; silica; nanoparticles; photocatalysis; protein adsorption; Nanostructured implants;

   Abstract : A great challenge of today’s implant development is to construct a surface that promotes tissue integration and avoids bacterial colonization. To avoid implant related infections, many argue that a surface promoting strong cell adhesion and tissue integration in favour for bacterial adhesion would solve the problem, the so-called race for the surface concept.

4. 2. Fluorescent Probes and Protein Misfolding: Methods and Applications

   Author : Irem Nasir; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein misfolding; fluorophores; filter-trap; site-specific fluorophore labeling; amyloid-beta; microscopic rate constants; solvatochromic probes; alpha-synuclein; lipid vesicles; nanoparticles; protein adsorption;

   Abstract : Protein misfolding is a frequently occurring event in living cells and without the quality control, the consequences are disasterous. In this thesis, we studied protein misfolding in vitro by employing a variety of fluorophores, to either detect the highly ordered aggregates of intrinsically disordered proteins/peptides or slight misfolding of a natively folded protein.

5. 3. Adsorption kinetics of cationic polyacrylamides on cellulose fibres and its influence on fibre flocculation

   Author : Daniel Solberg; KTH; []
   Keywords : Adsorption; bridging; cationic polymers; cellulose fibres; electrosteric stabilisation flocculation; ;

   Abstract : The adsorption of cationic polyacrylamide (C-PAM) and silicananoparticles onto a model surface of silicon oxide wascompared with the adsorption of C-PAM to fibres and theirinfluence on flocculation of a fibre suspension. An increase inionic strength affects the polyelectrolyte adsorption indifferent ways for these two systems. READ MORE

6. 4. Interactions of Mucins with Biopolymers and Drug Delivery Particles

   Author : Olof Svensson; Malmö högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mucin; chitosan; lactoperoxidase; multilayer; mucoadhesion; nanoparticles; ellipsometry;

   Abstract : The main components in the mucous gels apart from water are mucins, which are proteins with high molecular weights and an abundance of negatively charged oligosaccharide side chains. The aim of the investigations was to characterize interactions between mucins and other proteins that are present in the mucous gel, and also between mucins and components used in pharmaceutical formulations.

7. 5. Nanoparticle-based capillary electrochromatography

   Author : Peter Spégel; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; Analytisk kemi; Analytical chemistry; Nanoparticles; Molecularly imprinted polymers; Capillary electrochromatography;

   Abstract : This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. READ MORE
