  1. 21. Exploring microfluidics as a tool to study cell-biomaterial interactions

    Författare :Sarah-Sophia Carter; Gemma Mestres; Marlon Schneider; Uppsala universitet; []
    Nyckelord :Bone; Cement; Flow; Hydroxyapatite; In vitro; On-chip; Titanium; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Sammanfattning : Considering the tremendous amount of research on the development of novel biomaterials, relatively few of these have reached the patient. This can at least in part be explained by the lack of predictive power of the currently used in vitro models, which are nowadays recognized to be too reductionist to accurately predict in vivo complexity.

  3. 22. Glass Ionomer Cements with Improved Bioactive and Antibacterial Properties

    Författare :Song Chen; Håkan Engqvist; Wei Xia; Jie Zhou; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterial; glass ionomer cement; bioactivity; hydroxyapatite; monetite; calcium silicate;

    Sammanfattning : Dental restorative cements are placed in a harsh oral environment where they are subjected to thermal shock, chemical degradation, and repeating masticatory force. The ideal restorative dental cements should have superior mechanical properties, chemical stability, aesthetic, good handling properties, biocompatibility, antibacterial properties, and preferably bioactivity.

  4. 23. Nanofeatures of Biomaterials and their Impact on the Inflammatory Response

    Författare :Shiuli Pujari-Palmer; Marjam Ott; Håkan Engqvist; Matteo Santin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofeatures; alumina; hydroxyapatite; inflammation; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Nanomaterials offer an advantage over traditional biomaterials since cells naturally communicate via nanoscale interactions. The extracellular matrix, for example, modulates adhesion and cellular functions via nanoscale features. LÄS MER

  5. 24. Bioactive Coatings and Antibacterial Approaches for Titanium Medical Implants

    Författare :Oscar Janson; Ken Welch; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioactivity; antibacterial; titanium; hydrogen peroxide; hydroxyapatite; biomaterial; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : The aim of this thesis was to characterize and manufacture coatings and surfaces with antibacterial properties and retained or enhanced bioactivity and biocompatibility. The aim was also to study the optimal composition and parameters of mixtures for debridement of bacterial biofilms on titanium surfaces. LÄS MER

  7. 25. 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
