  2. 1. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces

    Author : Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Layer-by-layer; multilayer; adsorption; biopolymers; Chitosan; Heparin; Mucin; Albumin; Lysozyme; β-casein; SDS; QCM-D; Ellipsometri; DPI; TIRF; FRET; SFA; layer structure; solvent content; vertical diffusion; exponential growth; solid-liquid interface; deposition conditions; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. READ MORE

  4. 2. Antibodies and Antibody Mimics in Binding Assays

    Author : Ioana Wärnmark; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; ELISA; antibody; molecularly imprinted polymer; Biochemistry; Biokemi; Metabolism; metabolism; Biokemisk teknik; Polymer technology; Biochemical technology;

    Abstract : This thesis presents development of new analytical methods using antibodies and molecularly imprinted polymers (MIPs) in binding assays: 1) The high specificity of antibodies and the wide variety of efficient labels make immunoassay one of the most popular analytical techniques today. Enzyme-linked immunosorbent assay (ELISA) is most widely used, since the enzyme label can be used as a catalyst to provide very high signal amplification. READ MORE

  5. 3. Polymer Gels: Modeling the Swelling Behavior

    Author : Stefanie Schneider; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Polymerteknik; biopolymers; Polymer technology; binding isotherms; polyelectrolyte-surfactant interactions; discontinuous volume transition; gel swelling; Monte Carlo simulation; polyelectrolyte gels;

    Abstract : This thesis is concerned with the swelling behavior of polyelectrolyte gels. The thesis can be divided into two parts. Part one deals with the modeling and computer simulation of the gel swelling. READ MORE

  6. 4. Composite Materials in Molecular Imprinting Technology

    Author : Ecevit Yilmaz; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; immobilized template; molecularly imprinted polymer; composite material; polymerization method; heterogeneous imprinting; surface; morphology; Polymer technology; Polymerteknik; biopolymers;

    Abstract : Molecularly imprinted polymers (MIPs) are artificial plastic materials that mimic antibodies or enzymes. Like natural antibodies or enzymes, molecularly imprinted polymers can selectively bind target molecules or can promote catalytic reactions. READ MORE

  7. 5. Design of Cellulose-based Materials by Supramolecular Assemblies

    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.
