  4. 12. Interactions of Biopolymers and Metalcomplexes at Biological Interfaces

    Author : Jildiz Hamit Eminovski; Malmö högskola; []
    Keywords : Mucin; BSM; Microthrix parvicella; polyaluminium chloride; ellipsometry; QCM-D; AFM;

    Abstract : The present work concerns interaction between biopolymers at interfaces. Examples from real systems such as saliva and bacterial surfaces as well as model systems have been studied. READ MORE

  5. 13. Phospholipid membranes in biosensor applications : Stability, activity and kinetics of reconstituted proteins and glycolipids in supported membranes

    Author : Inga Gustafson; Gertrud Puu; Sven Lindskog; Peter Konradsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Phospholipid films; Liposomes; Membrane proteins; Glycolipids; Ellipsometry; Langmuir Blodgett LB ; Surface plasmon resonance SPR ; Resonant mirror RM ; Atomic force microscopy AFM ; Biosensors; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : In this study the formation of supported membranes onto planar solid supports has been investigated. The stability and activity of reconstituted membrane receptors has been studied. The potential use of such preparations in biosensor applications is discussed.The lipid films were made by the Langmuir Blodgett and by the liposome fusion techniques. READ MORE

  6. 14. 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. 15. Polyelectrolytes on Surfaces and their Complexes with Surfactants, Thermodynamics versus kinetics

    Author : Yulia Samoshina; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Polymer technology; Physical chemistry; SDS; amphiphilic polyelectrolytes; ellipsometry; reversibility; kinetics of adsorption; polyelectrolytes at solid-liquid interface; polyelectrolyte-oppositely charged surfactant complexes; biopolymers; Polymerteknik;

    Abstract : The interfacial properties of polyelectrolytes, mainly cationic with various content of amphiphilic groups, and their complexes with an oppositely charged surfactant, sodium dodecyl sulfate (SDS), have been investigated using time-resolved ellipsometry. This thesis focuses on the kinetics and reversibility aspects of polymer adsorption and the control of the adsorption by regulating the electrostatic interactions. READ MORE
