  1. 21. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology

    Författare :Fredrika Gullfot; Harry Brumer; Tuula Teeri; Jerry Ståhlberg; Mats Martinelle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; polysaccharide synthesis; Bioengineering; Bioteknik; Enzyme engineering; Enzymteknik; Bioorganical synthesis; Bioorganisk syntes; Biomaterials; Biomaterial;

    Sammanfattning : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

  3. 22. Investigating mucin interactions with diverse surfaces for biomedical applications

    Författare :Georgia Petrou; Thomas Crouzier; Anette Larsson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucus; mucin; protein adsorption; biomaterials; lubrication; mucoadhesion; 4RepCT; Bioteknologi; Biotechnology;

    Sammanfattning : Mucous membranes are covered with mucus, a viscoelastic hydrogel that plays an essential role in their protection from shear and pathogens. The viscoelasticity of mucus is owing to mucins, a group of densely glycosylated proteins. LÄS MER

  4. 23. Bio-inspired polysaccharide nanocomposites and foams

    Författare :Anna Svagan; Lars Berglund; Mats Stading; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cellulose; starch; microfibrillated cellulose; biomimetic; nanocomposite; nanocomposite foam; mechanical properties; Biomaterials; Biomaterial;

    Sammanfattning : Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. LÄS MER

  5. 24. Biomaterials for Promoting Self-Healing of Bone Tissue

    Författare :Sonya Piskounova; Jöns Hilborn; Tim Bowden; Simon Cool; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Osseointegration; implant coating; hyaluronan hydrogel; bone morphogenetic protein-2; hydroxyapatite; bone; delivery system; injectable; mixing; radioactive labeling; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : The present work addresses poor bone/implant integration and severe bone defects. In both conditions external stimuli is required for new bone to form. LÄS MER

  7. 25. Recombinant spider silk for biomedical applications - from functionalizing surfaces of synthetic materials to in vitro modelling of tissues

    Författare :Christos Panagiotis Tasiopoulos; My Hedhammar; Antonella Motta; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; recombinant spider silk; surface functionalization; in vitro tissue models; membrane-based models; barrier tissues; cell co-culture; tissue engineering; Bioteknologi; Biotechnology;

    Sammanfattning : Spider silk is a natural protein-based material known for its medicinal use and remarkable mechanical properties. Structures made thereof are both strong and elastic and have been shown to be favorable matrices for tissue engineering. LÄS MER
