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

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

    Abstract : 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. READ MORE

  5. 3. Functional Degradable Polymers by a Radical Chemistry approach

    Author : Jenny Undin; Ann-Christine Albertsson; Anna Finne-Wistrand; Jukka Seppälä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : One class of polymers that is inherently of great value for many applications is the aliphatic polyesters. Such polymers are very suitable for use as temporary guides, scaffolds, for tissue formation and other biomedical applications, due to their biocompatibility, degradability and appropriate mechanical properties.

  6. 4. Large scale synthesis of polyesters with low amount of residual tin

    Author : Anna Stjerndahl; Ann-Christine Albertsson; Johan Lind; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : Användningen av resorberbara polymerer för applikationer inom vävnadsersättning har ökat markant under de senaste decennierna. Tekniken innebär att celler får växa på ett polymert bärarmaterial och på så sätt återskapa skadad vävnad, och är ett lovande alternativ till många av de implantat som används idag. READ MORE

  7. 5. Organic Azides : Functional Molecules and Materials

    Author : Giampiero Proietti; Peter Dinér; Per I. Arvidsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; perfluorinated Aromatic Azide; Photoactivatable; fluorophores; aggregation-induced emission; sulfonimidamides; sulfoximes; chiral auxilary; organogel; azides reduction; Ni-B; Kemi; Chemistry;

    Abstract : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.
