  1. 1. Controlled axonal outgrowth and cell reactions to nanostructures

    University dissertation from Lund University

    Author : Fredrik Johansson; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Contact guidance; neuron; axon; fibroblast; macrophage; polymethylmethacrylate; porous silicon; nanowire; magnetic; immunoresponse; nanoimprint lithography; haptotaxis;

    Abstract : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. READ MORE

    Abstract : Popular Abstract in Swedish Denna avhandling beskriver utvecklingen av en teknik baserad på mikrodispensering, för att skapa proteinmönster som kan användas för styrning av axoner. Samma teknik vidareutvecklades för att kunna positionera dissocierade celler, bl.a. nervceller, på cellodlingsytor. READ MORE

  4. 4. Nanowires for Cell Research

    University dissertation from Solid State Physics, Lund University

    Author : Waldemar Hällström; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanotoxicology; Nanowires; Nanotubes; Nerve Cells; Cell Probing; Force Measurements; Nanotechnology; Axonal Guidance; Fysicumarkivet A:2010:Hällström;

    Abstract : Popular Abstract in Swedish Sammanfattning Den här avhandlingen handlar om gränsskiktet mellan nanoteknologi och cellbiologi, om hur celler och nanostrukturer påverkar varandra, och om hur man kan använda nanopinnar för att studera celler. Å ena sidan vill man kunna mäta egenskaper hos cellerna, det vill säga låta cellerna påverka pinnarna, å andra sidan vill man kunna styra cellerna – låta pinnarna påverka cellerna. READ MORE

  5. 5. Cell therapy for spinal cord injury, studies of motor and sensory systems

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Christoph Hofstetter; Karolinska Institutet.; Karolinska Institutet.; [2005]
