  1. 6. Fragment Based Drug Discovery with Surface Plasmon Resonance Technology

    Författare :Helena Nordström; Helena Danielson; Gregg Siegal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fragment based drug discovery; SPR biosensor; matrix metalloproteinase-12; HIV-1 protease; resistance;

    Sammanfattning : Fragment based drug discovery (FBDD) has been applied to two protease drug targets, MMP-12 and HIV-1 protease. The primary screening and characterization of hit fragments were performed with surface plasmon resonance -technology. Further evaluation of the interaction was done by inhibition studies and in one case with X-ray crystallography. LÄS MER

  3. 7. Active magnetoplasmonics for nanoscale distances sensing

    Författare :Irina Zubritskaya; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cobalt; magnetoplasmonics; plasmon ruler; magneto-optical Kerr effect MOKE ; nickel; dimer; localized surface plasmon resonance;

    Sammanfattning : Magnetoplasmonics is an emerging field within nano-photonics that operates with the combination of propagating or localized surface plasmons and magnetism. Active and adaptive magnetoplasmonic components that are capable of controlling light on the nanoscale with external weak magnetic fields are envisioned to push the development of integrated photonic circuits, high-density data storage, or the advanced schemes for bio- and chemo-sensing.

  4. 8. Time-resolved plasmonics in designed nanostructures

    Författare :Eleonora Lorek; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasmon; Nanostructure fabrication; High-order harmonic generation; Photoemission electron microscopy; Focused ion beam; Fysicumarkivet A:2016:Lorek;

    Sammanfattning : A metal nanoparticle can be considered as consisting of a base of positive ion cores and a sea of free electrons. When the free electrons are displaced, for example, by an incident electric field, a restoring force acts on the electrons. The electrons may then oscillate back and forth until equilibrium is reached. LÄS MER

  5. 9. Affinity Biosensors for Carbahydrate-Protein Interactions using Surface Plasmon Resonance

    Författare :Christina Jungar; Bengt Danielsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : There is an increasing need for fast, accurate, and easy-to-use biosensors for applications in environmental, food, and pharmaceutical industry. In these thesis the interactions between immunoglobulins and lectins with their corresponding carbohydrate antigens are studied using surface plasmon resonance (SPR). LÄS MER

  7. 10. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing

    Författare :Christoph Langhammer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticle; hydrogen storage; aluminum; hydrogen sensing; localized surface plasmon resonance; platinum; nanostructure; palladium; nanoparticle plasmon;

    Sammanfattning : The interaction of light with sub-wavelength noble metal nanoparticles and nanostructures has developed into one of the most vibrant themes of nanoscience during the past decade. The optical properties of metal nanoparticles are dominated by so-called nanoparticle plasmons or localized surface plasmon resonances (LSPR). LÄS MER
