  1. 1. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes

    Författare :Pegah Sadat Nabavi Zadeh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluorescence spectroscopy; dynamics; mesoporous silica; Immunogold staining; Transmission electron microscopy; anisotropy; microviscosity; real-time monitoring; Cy5.; Förster resonance energy transfer; Enzyme immobilization; Cy3;

    Sammanfattning : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. LÄS MER

  3. 2. First As Probe, Then As Function - Fluorescence in Bio-inspired Nanotechnology

    Författare :Jonas Hannestad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; lipid membrane; bio-inspired; FRET; light-harvesting; spectroscopy.; fluorescence; nanotechnology; single molecule fluorescence spectroscopy; DNA;

    Sammanfattning : In this thesis, I demonstrate how fluorescence can be used in the context of bio-inspired nanotechnology, both as an indirect probe and as a function in itself. By combining principles and molecules from three different bio-molecular systems, DNA, bacterial light-harvesting complexes and cell membranes, I have constructed nano- and microscale systems for long-range excitation energy transfer, light-harvesting and reaction control.

  4. 3. Evolutionary aspects of the immunoglobulin heavy chain constant locus

    Författare :Hodjatallah Rabbani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human Ig heavy chain constant locus (IGHC) is composed of nine functional and two pseudo genes. Extensive polymorphism consisting of deletions, duplications and point mutations have been observed in this locus. LÄS MER

  5. 4. Transplantation of mesenchymal stem cells and injections of microRNA as therapeutics for nervous system repair

    Författare :Mallappa K. Kolar; Lev N. Novikov; Paul J. Kingham; Mikael Wiberg; Elisabet Åkesson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spinal cord injury; peripheral nerve injury; mesenchymal stem cells; regeneration; neurotrophic factor; angiogenic factor;

    Sammanfattning : Traumatic injuries to the spinal cord (SCI) and peripheral nerve (PNI) affect several thousand people worldwide every year. At present, there is no effective treatment for SCI and despite continuous improvements in microsurgical reconstructive techniques for PNI, many patients are still left with permanent, devastating neurological dysfunction.
