  1. 1. Porous degradable polyester scaffolds

    Författare :Peter Plikk; Ann-Christine Albertsson; Johan Lind; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; copolymer; porous scaffold; ring-opening polymerization; electron beam; gamma irradiation; Polymerteknologi; Chemistry; Kemi;

    Sammanfattning : Tissue engineering is a growing research field in which degradable porous scaffolds are used to regenerate tissue from the patients own cells. The problems due to donor shortage or the lack of full property restoration from prosthetic implants can thereby be overcome. LÄS MER

    Sammanfattning : There is an increasing demand for new materials in biomedical applications with material properties that are highly specific for each application area. The search for new materials requires the creation of materials with suitable mechanical properties, functionalities, three-dimensional structures and a controlled degradation profile. LÄS MER

  7. 5. Synthesis of Biomedical Polymers and Scaffold Design

    Författare :Therese Tyson; Ann-Christine Albertsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; tin alkoxide initiator; stannous octoate; poly p-dioxanone ; copolymer; L-lactide; trimethylene carbonate; degradable porous scaffold; Polymer chemistry; Polymerkemi;

    Sammanfattning : This work has focused on the development of new improved synthesis methods of biodegradable aliphatic polymers and on the preparation of porous scaffolds for tissue engineering applications. The aim of the first part of the work was the synthesis of poly(p-dioxanone) (PPDX) homopolymers with high molecular weights using the cyclic tin alkoxide initiator 1-di-n-butyl-1-stanna-2,5-dioxacyclopentane.
