  1. 6. Hyaluronan Derivatives and Injectable Gels for Tissue Engineering

    Författare :Kristoffer Bergman; Tim Bowden; Jöns Hilborn; Jeffrey Hubbell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; Hydrogel; Tissue Engineering; Scaffold; Minimally invasive strategy; Bone morphogenetic protein; Hydroxyapatite; Bone; Cartilage; Tendon; Polymer chemistry; Polymerkemi;

    Sammanfattning : The present work describes the preparation of hyaluronan derivatives and hydrogels with potential use in tissue engineering applications. A potentially injectable hydrogel consisting of hyaluronan and collagen was successfully used to grow neurons in vitro by encapsulation of neural stem and progenitor cells. LÄS MER

    Sammanfattning : Covalent cross-linking chemistry is currently exploited in the preparation of biomaterial for biomedical applications. Choice of these chemistries for the preparation of biomaterials and bioconjugates strongly influences the biological output of these materials. LÄS MER

  4. 8. Relating the Bulk and Interface Structure of Hyaluronan to Physical Properties of Future Biomaterials

    Författare :Ida Berts; Jöns Hilborn; Adrian R Rennie; Giovanna Fragneto; John W White; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; structure; bulk; interface; small-angle neutron scattering; neutron reflection; hydrogel; grafting; nanoparticles; protein interactions;

    Sammanfattning : This dissertation describes a structural investigation of hyaluronan (HA) with neutron scattering techniques. HA is a natural biopolymer and one of the major components of the extracellular matrix, synovial fluid, and vitreous humor. LÄS MER

  5. 9. Composite Regenerative Scaffolds

    Författare :Elle Edin; Jöns Hilborn; May Griffith; Alicia El Haj; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nerve; neurite; regeneration; PEDOT; PEDOT:Tosylate; electrostimulation; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Regenerative medicine and tissue engineering solutions of heavily innervated tissues are at this point lacklustre. This thesis expands our knowledge of appropriate acellular scaffolds for tissue repair in general and nerve regeneration in particular. LÄS MER

  7. 10. Biosensing platforms using graphene based bioreactive nanostructures with various dimensions

    Författare :Yuanyuan Han; Klaus Leifer; Jöns Hilborn; Hu Li; Boukherroub Rabah; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; nanoparticles; nanostructure; biosensors;

    Sammanfattning : Nanomaterials have brought new aspects and improvements to the biosensing field due to their unique physical and chemical properties that are not shown in the bulk state. This thesis focuses on concepting, developing and testing of biosensors where nanomaterials including graphene gold nanoparticles (AuNPs) and magnetic nanoparticles (MNPs) constitute the biosensors.
