  2. 1. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

    Author : Dorota Thid; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

    Abstract : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.

  5. 3. Microfluidics in Surface Modified PDMS : Towards Miniaturized Diagnostic Tools

    Author : Sara Thorslund; Fredrik Nikolajeff; Jonas Bergquist; Elisabeth Verpoorte; Uppsala universitet; []
    Keywords : Materials science; µTAS; micro total analysis system; PDMS; poly dimethylsiloxane ; microfluidics; heparin; blood filtration; on-chip; ESI-MS; desalting; QCM-D; biocompatible; CD4; capillary flow; lab-on-chip; microfabrication; enrichment; point-of-care; hydrophilic; oxidation; Materialvetenskap;

    Abstract : There is a strong trend in fabricating miniaturized total analytical systems, µTAS, for various biochemical and cell biology applications. These miniaturized systems could e.g. gain better separation performances, be faster, consume less expensive reagents and be used for studies that are difficult to access in the macro world.

    Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.
