  1. 1. Development of New Bacteria-Reducing Surfaces

    Författare :Josefin Illergård; Monica Ek; Lars Wågberg; Eva Blolmberg; Ute Römling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antibacterial; polyelectrolyte multilayers; polyvinylamine; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : In recent years, antibacterial surfaces have been a subject of increased interest. Especiallyinteresting are non-leaching, contact-active surfaces that physically disrupts the bacterialcell using immobilised cationic polymers. Thus the risks of bacterial resistance and discharge of hazardous biocides is minimised. LÄS MER

  3. 2. The creation of antibacterial fibres through physical adsorption of polyelectrolytes

    Författare :Josefin Illergård; Monica Ek; Lars Wågberg; Malmsten Martin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antibacterial; polyelectrolyte multilayers; polyvinylamine; contact-active antibacterial surfaces;

    Sammanfattning : Contact-active antibacterial surfaces with irreversibly attached antibacterial com-pounds are a sustainable alternative to traditional biocides. No chemicals are released into nature and the antibacterial mechanism reduces the risk of the evolution of re-sistant bacteria. LÄS MER

  4. 3. On the effects of structure and function on protein evolution

    Författare :Kristoffer Illergård; Arne Elofsson; Nir Ben-Tal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein; structure; function; evolution; membrane; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : Many proteins can be described as working machines that make sure that everything functions in the cell. Their specific molecular functions are largely dependent on their three-dimensional structures, which in turn are mainly predetermined by their linear sequences of amino acid residues. LÄS MER

  5. 4. Development of Non-leaching Antibacterial Approaches on Cellulose-based Substrates and Their Mechanisms

    Författare :Chao Chen; Monica Ek; Josefin Illergård; Stefan Spirk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Layer-by-layer; antibacterial; cellulose materials; Chemical Engineering; Kemiteknik;

    Sammanfattning : The layer-by-layer (LbL) technique is becoming a powerful tool that has been applied in many surface coatings and functionalizations in recent years. It has many advantages including a fast and mild process, the flexibility of choice of substrate, and the easiness to scale-up. LÄS MER

  7. 5. Bio-based preparation of nanocellulose and functionalization using polyelectrolytes

    Författare :Jonatan Henschen; Monica Ek; Josefin Illergård; Dongfang Li; Emily Cranston; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; cellulose nanocrystals; oxalic acid; polyvinylamine; layer by layer; cellulose oxalate; antibacterial; Cellulosa nanofibriller; cellulosa nanokristaller; oxalsyra; polyvinylamin; lager på lager; cellulosa oxalat; antibakteriell; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Nanocellulosa, som kan utvinnas från skogsråvara, har de senaste åren fått mycket uppmärksamhet för sina intressanta egenskaper och breda användningsområde. Studierna i denna avhandling syftar till att vidga möjligheterna att använda nanocellulosa i olika applikationer. LÄS MER
