  1. 1. Macrophage-material surface interactions

    Författare :Christina Gretzer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

    Sammanfattning : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. LÄS MER

  3. 2. Engineering 3D degradable pliable scaffolds for adipose tissue regeneration : Advancing cell-material interactions by understanding the influence from thermal, chemical, mechanical properties and scaffold design

    Författare :Shubham Jain; Anna Finne-Wistrand; Kamal Mustafa; Mikael Hedenqvist; Lauren Flynn; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradable polymers; 3D scaffolds; adipose tissue regeneration; cell-material interaction; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In soft tissue defects that arise due to trauma, tumor resections and complex burns, a significant loss in adipose tissue remains a considerable challenge due to the insufficient regenerative capacity of the tissue. This thesis focuses on assessing cell-material interactions between degradable 3D polymer scaffolds with different designs and adipose tissue-derived stem cells. LÄS MER

  4. 3. Structure Dependent Chemical and Biological Interactions of Poly(urethane urea)s

    Författare :Katrin Gisselfält; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomaterial; synthesis; hydrogen bonding; biological interactions; structure; properties; poly urethane urea ;

    Sammanfattning : Poly(urethane urea)s, PUURs, are widely used in both industrial and biological applications because of excellent physical and mechanical properties and good biocompatibility in a variety of applications. Both the processing and the tailoring of specific properties of PUUR demand great knowledge of structure-property relationships. LÄS MER

  5. 4. Nanowires in Cell Biology

    Författare :Henrik Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phase holographic microscopy; Nanowires; living cells; cell injection; Fysicumarkivet A:2014:Persson;

    Sammanfattning : This thesis explores the interactions between cells and nanowires, to increase our understanding of how cells are affected and how they can be manipulated by these one-dimensional, semiconductor crystals (lengths 1-10 µm, diameters .... LÄS MER

  7. 5. Synthesis of functional degradable polymers by radical ring-opening polymerization

    Författare :Jenny Undin; Ann-Christine Albertsson; Mats Johansson; Monica Ek; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tissue engineering; ring-opening polymerization; 2; 2´-azoisobutyronitrile; cyclic ketene acetals; 2-methylene- 1; 3; 6-trioxocane; 2-methylene- 1; 3-dioxepane; vinyl acetate; coopolymerization;

    Sammanfattning : The increased demand for understanding cell-material interactions and subsequently create personalized implants for tissue engineering has resulted in an increased interest in developing new monomers with functional groups. The focus of the work presented in this thesis has been on the synthesis of functional monomers and the polymerization of these into functional amorphous aliphatic polyesters. LÄS MER
