  1. 1. Degradable copolymers in additive manufacturing: controlled fabrication of pliable scaffolds

    Författare :Astrid Ahlinder; Anna Finne Wistrand; T. Christian Gasser; Tiziana Fuoco; Minna Kellomäki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Inom vävnadsregenerering är produktionen av väldefinieradematriser med en porös arkitektur av nedbrytbara polymerer av stortintresse, dessa kan nu skapas genom additiva tillverkningsprocesser. Vidadditiv tillverkning krävs ett smalt munstycke för att skapa detaljrikastrukturer och detta ställer krav på att de reologiska egenskapernaanpassat. LÄS MER

  3. 2. Microwave heating effects on degradation and migration of additives from polypropylene packaging

    Författare :Jonas Alin; Minna Hakkarainen; Jiebing Li; Anna Finne Wistrand; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : The effect of different food types, polymer qualities and microwaves on the overall and specific migration during microwave heating of plastic packaging was investigated to better understand the packaging-food interactions and the effect of microwaves on food packaging. This work focuses on the migration of chemical compounds to food simulants from commercially available polypropylene packages. LÄS MER

  4. 3. Polyester scaffold: Material design and cell-protein-material interaction

    Författare :Staffan Dånmark; Anna Finne-Wistrand; Ann-Christine Albertsson; Kamal Mustafa; Pentti Tengvall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Tissue engineering has emerged as a valid approach for the regeneration and restoration of bone defects. The concept of bone tissue engineering includes degradable scaffolds, osteogenic cells and osteoinductive growth factors either alone or in any combination of these three. LÄS MER

  5. 4. Synthesis and Characterization of Self-Assembling Low Molecular Weight Copolymers for Bioengineering Applications

    Författare :Jenny Fagerland; Anna Finne-Wistrand; Tim Bowden; Natalia Andronova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cooligomers; bioengineerng applications; polymer synthesis;

    Sammanfattning : The constant need for improved biomedical materials and the interest in producing materials with similar properties to the extracellular matrix in different tissues has resulted in increasing interest in research on hydrogels. Over the last decade self-assembling copolymers have been of particular interest since they form hydrogels in response to external stimuli such as temperature. LÄS MER

  7. 5. Synthesis of degradable aliphatic polyesters: strategies to tailor the polymer microstructure

    Författare :Jenny Fagerland; Anna Finne-Wistrand; David Kaplan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer synthesis; enzymatic synthesis; degradable polyesters; peptides; scaffolds; Chemical Engineering; Kemiteknik;

    Sammanfattning : Key factors for successful tissue engineering are the synthesis and design of the scaffold materials. Aliphatic polyesters have been studied and often used as scaffold materials for tissue engineering. However, their lack of biological cues and degradation under high-temperature processing (e.g. LÄS MER
