    Sammanfattning : Within healthcare there is a market pull for biomedical devices that can rapidly perform laboratory processes, such as diagnostic testing, in a hand-held format. For this reason, biomedical devices must become smaller, more sophisticated, and easier to use for a reasonable cost. LÄS MER

  3. 2. Thiol-Ene CHemistry and Dopa-Functional Materials towards Biomedical Applications

    Författare :Kristina Olofsson; Anders Hult; Michael Malkoch; Anders Daugaard; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; DOPA; biomedical; UV; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Thiol-ene chemistry is versatile and efficient and can be used as a powerful tool in polymer synthesis. In this thesis, the concept of thiol-ene chemistry has been central, where it has been explored as a tool for the synthesis of well-defined hydrogels and dopa-functional materials towards biomedical applications; such as hydrogels, primers for adhesive fixation of bone fractures, self-healing gels, and micelles for drug-delivery.

    Sammanfattning : Nowadays, there is an urgent need to decrease our dependence on fossilresources and shift towards the use of renewable resources for advancingsustainable development. Utilizing renewable and bio-based raw materials,such as lignocellulosic biomass, for designing new materials is a promisingapproach to promote this objective. LÄS MER

  5. 4. Dendrimers : Synthesis, Characterization and Use in Thiol-Ene Networks

    Författare :Camilla Nilsson; Eva Malmström; Andreas Heise; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer; molecular physics; Polymer chemistry; Polymerkemi;

    Sammanfattning :  Dendrimers are perfectly branched, well-defined macromolecules with a layered structure and a large amount of peripheral end groups. The high functionality in combination with the possibility of dendrimers to adopt a globular shape at high molecular weights, gives them very unique properties. LÄS MER

  7. 5. Thiol-Ene/Yne Adhesives for Tissue Fixation

    Författare :Viktor Granskog; Michael Malkoch; Philip Messersmith; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The utilization of adhesives in surgery has not reached its full potential and research in the field is encouraged by the surgeons’ desire for improved alternatives to today’s tissue fixation strategies. Here, adhesive resins based on thiol-ene coupling (TEC) chemistry or thiol-yne coupling (TYC) chemistry are exploited to develop tissue adhesives that cure fast and on-demand via photoinitiation.
