  1. 1. Attenuation of acute inlammatory responses by surface nanotopography

    Författare :Mats Hulander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; nanotopography; gradient nanotopography; immune complement; platelets;

    Sammanfattning : The interaction between biology and non-viable surfaces is crucial for many organisms and cells. For example, bacterial cells need to adhere to mineral surfaces in the soil, plants climb and adhere to walls and marine organisms produce adhesives to cling to underwater rocks etc. LÄS MER

  3. 2. On osseointegration in response to controlled surface nanotopography

    Författare :Dimitrios Karazisis; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in vivo; nanotopography; osseointegration; topography;

    Sammanfattning : Knowledge about the biological responses provoked by the surface modification of titanium implants on the nanoscale is still in its infancy. Although in vitro studies claim superior effects considering higher adhesion and proliferation of osteoblasts in the short term and even differentiation towards the osteogenic cell lineage in the long term, these responses do not necessarily reflect the actual outcome in the complex in vivo environment.

  4. 3. Effect of Surface Nanotopography on Blood-Biomaterial Interactions

    Författare :Natalia Ferraz; Marjam Ott; Jaan Hong; Jan Carlsson; Tom Eirik Mollnes; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoporous alumina; nanotopography; biomaterial; platelets; complement system; macrophages; whole blood; inflammatory response; Chemistry; Kemi; Immunobiology; Immunbiologi; Immunologi; Immunology; Materialvetenskap; Materials Science;

    Sammanfattning : Biologically inspired materials are being developed with the aim of improving the integration of medical implants and minimizing non-desirable host reactions. A promising strategy is the design of topographically patterned surfaces that resemble those found in the extracellular environment. LÄS MER

  5. 4. In vivo and in vitro studies of polyetheretherketone: bone formation, inflammatory response and biofilm formation

    Författare :Sargon Barkarmo; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PEEK; polyetheretherketone; hydroxyapatite; nanotopography; osseointegration; cytokines; biofilms; biomaterials; dental materials; titanium; nanocoated;

    Sammanfattning : In prosthetic dentistry, restorative materials are used to replace missing teeth and tissues, so as to maintain oral functionalities and comfort for the patient. Depending on the clinical problem, metals, ceramics or polymers, are used both in dentistry and orthopedics. LÄS MER

  7. 5. Coarse-Grained Modelling of Protein Adsorption

    Författare :Kristin Hyltegren; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered proteins; histatin 5; fibrinogen; protein adsorption; nanotopography; ellipsometry; Monte Carlo simulations; Coarse-grained modelling; charge regulation;

    Sammanfattning : The adsorption of proteins is a very common phenomenon, happening almost always when a protein solution comes into contact with a solid. However, it is far from always clear what the results of adsorption will be in terms of adsorbed amount, protein orientation, and protein conformation. LÄS MER
