  1. 1. Self-organization of nanoparticles - implications for interface biology

    Författare :Anders Lundgren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; self-organization; self-assembly; nanostructure; nanopatterns; cell surface interactions; chemical gradients;

    Sammanfattning : Cells bind to their surroundings via proteins displayed on the cell surface. These interactions support the cells and are important for many cellular processes, e.g. cell migration during morphogenesis, wound healing and cancer metastasis. LÄS MER

  3. 2. Nanostructured Artificial Biointerfaces

    Författare :Hossein Agheli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal Lithography; Electrostatic Self Assembly; Nanofabrication; Cell;

    Sammanfattning : AbstractThe interactions occurring between biological systems and the surface of biomaterials hasbeen an area of strong research focus for a number of decades. There has been a realisation ofthe importance of macromolecular interactions and a consequent need to understandbiointerfacial events at the nanometer length-scale. LÄS MER

  4. 3. Direct Nanoprototyping of Functional Materials via Focused Electron Beam

    Författare :Anastasia Riazanova; Lyubov M. Belova; Cornelis W. Hagen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBID; nanoprototyping; nanopatterning; nanoscale; nanostructure; purification; Au; Co; SiO2; dimethyl gold acetylacetonate; dicobalt octacarbonyl; TEOS; Dual Beam;

    Sammanfattning : During recent years the demand for nanoscale materials with tailor-made functional properties as bulk species, is continuously and progressively rising for such fields as e.g. micro- and nano-electronics, plasmonics, spintronics, bio-technology, bio-sensing and life sciences.

  5. 4. 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.

  7. 5. Nucleic acid tools for detection and characterization of biological systems

    Författare :Ioanna Smyrlaki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nucleic acids, DNA and RNA, are naturally occurring biopolymers synthetized by cells to store and propagate genetic information. They can be found in eukaryotic cells, bacteria, archaea and viruses and, thanks to the development of synthetic chemistry techniques, they can be synthetized with relative ease on demand in the laboratory.
