  1. 6. Engineering and Functionalization of Degradable Scaffolds for Medical Implant Applications

    Författare :Yang Sun; Anna Finne-Wistrand; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tissue engineering; nanodiamond; scaffold; bioreactor; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The treatment of bone defects is facing the situation of lacking donations for autotransplantation. As a valid approach, scaffold-based tissue engineering combines the construction of well-defined porous scaffolds with advanced cell culturing technology to guide tissue regeneration. LÄS MER

  3. 7. Tissue engineering in blood vessels

    Författare :Gisela Helenius; Göteborgs universitet; []
    Nyckelord :tissue engineering; vascular graft; endothelial cells; smooth muscle cells; thrombogenicity; mechanical properties; scaffold; bacterial cellulose;

    Sammanfattning : Severely occluded coronary- and peripheral arteries, caused by atherosclerotic plaques, are treated with bypass surgery. Autologous veins are the most commonly used replacement graft. Among the patients that need a vascular bypass, 5-10% lack appropriate replacement veins due to previous surgery of bad quality of the vessels. LÄS MER

  4. 8. Chondrocytes Differentiation- Biological and Biomaterial Perspectives

    Författare :Hanna Stenhamre; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; scaffold.; chondrocyte implantation; cartilage tissue engineering; dedifferentiation; redifferentiation;

    Sammanfattning : Articular cartilage is an avascular tissue and once injured it does not heal spontaneously. A successful tissue engineering approach for cartilage reconstruction is autolougus chondrocyte implantation (ACI). LÄS MER

  5. 9. Integration of Electrospun Materials in Microelectronic and Biomedical Applications

    Författare :Björn Carlberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; electrospinning; interpenetrating phase; stem cell; photolithography; patterning; thermal management; thermal interface material; scaffold;

    Sammanfattning : This thesis demonstrates the use of electrospinning and the novel properties of electrospunmaterials in two fields.The microelectronics industry has identified thermal interface materials as one of themajor bottlenecks hindering further integration at packaging level. LÄS MER

  7. 10. Cellulose derived carbon dots : From synthesis to evaluation as multifunctional building blocks in biomedical scaffolds

    Författare :Nejla Benyahia Erdal; Minna Hakkarainen; Jukka Seppälä; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; microwave; carbon dots; polycaprolactone; scaffold; mineralization; drug loading; cellulosa; mikrovågor; kolnanopartiklar; polykaprolakton; stödmatris för vävnadsregenerering; mineralisering; läkemedelsbärare; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The implementation of biobased and biodegradable polymeric materials in biomedical applications is often coupled with issues related to their insufficient mechanical properties or limited bioactivity. In this thesis, a perspective on valorization of biomass is presented, demonstrating the transformation of cellulose into biobased carbon nanomaterials with the potential to serve as multifunctional property enhancers in polycaprolactone (PCL) scaffold materials for tissue engineering.
