  2. 1. Nanostructured Artificial Biointerfaces

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

    Abstract : 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. READ MORE

  4. 2. The Mechanisms of Exocytosis Studied in Cells and Models with Amperometry

    Author : Lisa J. Mellander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exocytosis; Electrochemistry; Cells; Cell models; Phospholipids;

    Abstract : Exocytosis is the universal basis for neuronal communication, allowing the controlled release of neurotransmitter molecules from the presynaptic cell. Exocytosis has been widely studied in many systems. However, the details of this vital process are not fully understood. READ MORE

  5. 3. On the operation of light-emitting electrochemical cells

    Author : E. Mattias Lindh; Ludvig Edman; Thomas Wågberg; Thomas Lanz; Sebastian Reineke; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Artificial Light; Organic Electronics; Light-emitting Electrochemical Cells; Electrochemical Doping; Thin-film Optical Model; Optical Modes;

    Abstract : We are in the midst of a technological revolution that permeates nearly all human activities; artificial light is one of the most visible contributors in this societal change. If more efficient, green, and versatile light sources can be developed, they might improve the life of millions of people around the world while causing minimal damage to our climate and environment.

  6. 4. Manipulating neural stem cells

    Author : Malin Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The stem cell field is a fairly young but fast growing scientific field. Our understanding of stem cells has changed tremendously over the last couple of decades. This in mainly due to the development of new techniques that has enabled us to study stem cells from a completely new perspective. READ MORE

  7. 5. Nerve gap repair by the use of artificial conduits and cultured cells

    Author : Daniel Kalbermatten; Mikael Wiberg; Ulrich Mennen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose stem cells; cell matrix; fibrin; nerve conduit; nerve gap; Surgery; Kirurgi; kirurgi; Surgery;

    Abstract : Peripheral nerve injuries are often associated with loss of nerve tissue and require autologous nerve grafts to provide a physical substrate for axonal growth. This thesis investigates the use of fibrin as both a tubular conduit to guide nerve regeneration and also as a matrix material to suspend various regenerative cell types within/on poly-3-hydroxybutyrate (PHB) nerve conduits.
