  1. 1. Bioactive adsorbates on gold surfaces : structural properties and bio-interaction studies

    Författare :Rodrigo Jr Petoral; Hans Siegbahn; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis investigates the properties of biomolecular, model adsorbates on gold such as amino acid derivatives, peptides and related organic molecules. Subsequent bin-interaction studies were also conducted. LÄS MER

  3. 2. On possibly bioactive CP titanium implant surfaces

    Författare :Anna Göransson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium implants; surface modification; bioactivity; bone tissue; cell culture;

    Sammanfattning : Background Osseointegrated titanium implants are routinely used in clinical dentistry. Although the overallclinical results are good, there are situations when an improved implant healing is desirable, for instance incompromised bone or in order to decrease healing time. LÄS MER

  4. 3. Expanded knowledge on silk assembly for development of bioactive silk coatings

    Författare :Linnea Nilebäck; My Hedhammar; Renko de Vries; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recombinant spider silk; Self-assembly; Biomaterial; Implant coating; Functionalization; Multi-functional; Bioactive; Cell culture scaffold; Antibacterial; Bioteknologi; Biotechnology;

    Sammanfattning : Silk is a fascinating natural material made from proteins that self-assemble through structural rearrangements into one of the toughest materials known. As silk is protein-based, durable and elastic, it has many features that makes it suitable as a scaffold material for tissue engineering. LÄS MER

  5. 4. Understanding Composition–Structure–Bioactivity Correlations in Bioactive Glasses

    Författare :Yang Yu; Mattias Edén; Laurent Delevoye; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioactive glasses; Phosphosilicate glasses; Borophosphosilicate glasses; Solid-state NMR spectroscopy; Glass structure; Fourier-transform infrared spectroscopy; Hydroxyapatite; Amorphous calcium phosphate; Apatite formation; In vitro bioactivity testing; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Bioactive glasses integrate with bone/tooth tissues by forming a layer of hydroxy-carbonate apatite (HCA), which mimics the composition of bone mineral. In the current thesis, we investigated composition–structure–bioactivity correlations of phosphosilicate and borophosphosilicate (BPS) glasses. LÄS MER

  7. 5. Bio-Nano Interactions : Synthesis, Functionalization and Characterization of Biomaterial Interfaces

    Författare :Yixiao Cai; Xia Wei; Mikael Karlsson; Martin Andersson; Uppsala universitet; []
    Nyckelord :Bioactive surfaces; nanocrystalline diamond; hydroxyapatite; protein secondary structure; protein absorption; auditory neurons; single crystalline rutile; nano morphology; surface functionalisation; in vitro biomineralisation; translucent nano-ceramics; bio-window material; material characterisation.; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization.
