  1. 1. Null Ellipsometry and Protein Adsorption to Model Biomaterials

    Författare :Johan Benesch; Thomas Arnebrant; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : When implants are inserted into the human body cascades of events become started that will determine the outcome of wound healing and ultimately the success of the implantation. The events start with the adsorption of small molecules, and proteins that may be activated (enzymes) or are able to activate cells of the immune defense and the healing process. LÄS MER

  3. 2. Interaction Studies in Complex Fluids with Optical Biosensors

    Författare :Jenny Carlsson; Bo Liedberg; Kjell Janné; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Type 1 diabetes; Insulin; Lectin panel; Ellipsometry; Meat juice; Serum proteins; Chemistry; Kemi;

    Sammanfattning : In this thesis interactions in complex fluids, such as serum and meat juice, were analysed with optical biosensor techniques.Panels of lectins immobilised on gold surfaces were used for investigation of differences in protein glycosylation pattern in sera and meat juices between various species.

  4. 3. Controlling DNA compaction and the interaction with model biomembranes

    Författare :Marie-Louise Ainalem; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

    Sammanfattning : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. LÄS MER

  5. 4. Theoretical and Experimental Studies of Polymer Adsorption and Polymer Mediated Interactions

    Författare :Fei Xie; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte; Adsorption; Colloid; Polymer; Dispersion; Interation; Ellipsometry; Monte Carlo Simulation; Classical Density Functional Theory;

    Sammanfattning : Polyelectrolyte adsorption and polymer mediated interactions in different colloidal polymer systems have been studied in this work. Theoretical methods and experimental techniques are combined, in order to obtain more general reliable results, as well as a deep understanding of the molecular mechanisms that are responsible for the observed behaviors.

  7. 5. Adsorption of nonionic amphiphiles to solid surfaces

    Författare :Johanna Brinck; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; silica; solubilisation; self assembly; ellipsometry; mixed micelles; surfactant; kinetics; Adsorption; desorption; Fysikalisk kemi;

    Sammanfattning : In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. LÄS MER
