  2. 1. Protein and Cell Interactions with Nanostructured Surfaces

    Author : Emma Westas; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; titanium dioxide; implant associated infections; metabolomics; cellular interactions; hydroxyapatite; immune complement activation; silica; nanoparticles; photocatalysis; protein adsorption; Nanostructured implants;

    Abstract : A great challenge of today’s implant development is to construct a surface that promotes tissue integration and avoids bacterial colonization. To avoid implant related infections, many argue that a surface promoting strong cell adhesion and tissue integration in favour for bacterial adhesion would solve the problem, the so-called race for the surface concept.

  4. 2. Flame nanoengineering of antibiofilm surfaces for medical implants

    Author : Felix J. Geissel; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Infection of bone implants is a major problem in the Healthcare sector today. Over the last years it has started to become more problematic due to biofilm formation and increasing antimicrobial resistance (AMR). A biofilm provides mechanical shielding to bacteria by ingulfing them leading to a less effective treatment with antibiotics. READ MORE

  5. 3. Integrated biomechanical, electronic and topographic characterization of titanium dental implants

    Author : Johanna Löberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface roughness parameters; 3D-SEM; AFM; Interfacial shear strength; Impedance spectroscopy; Cyclic voltammetry; SBF; MG-63; TiO2-nanoparticles;

    Abstract : Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored in the bone to withstand the forces induced by for example chewing. READ MORE

  6. 4. Nanoscale Osseointegration : Characterization of Biomaterials and their Interfaces with Electron Tomography

    Author : Kathryn Grandfield; Håkan Engqvist; Peter Thomsen; Anders Palmquist; Alexandra Porter; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron tomography; transmission electron microscopy; hydroxyapatite; titanium; titania; bone; implant; osseointegration; interface; mesoporous; Materialvetenskap; Materials Science;

    Abstract : Bone response is one of the key determining factors in the overall success of biomaterials intended for bone regeneration and osseointegration. Understanding the formation of bone at an implant surface may lead to the improved design of biomaterials for the future. READ MORE

  7. 5. Molecular and cellular interactions on noble metal nanopatterned surfaces − applications towards bone, soft tissue and infection control

    Author : Sara Svensson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanotopography; noble metals; titanium; biocompatibility; osseointegration; inflammation; host defence; monocytes; infection control; antimicrobial; staphylococci;

    Abstract : Biomaterial-associated infection is recognised as one of the main risks for failure of medical devices. The presence of a foreign material in tissues has been suggested to compromise the ability of host cells to eradicate infection. READ MORE
