  1. 1. Imaging surface plasmon resonance

    Författare :Olof Andersson; Bo Liedberg; Fredrik Björefors; Thomas Ederth; Jiří Homola; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi;

    Sammanfattning : The central theme of this thesis is the use of imaging Surface Plasmon Resonance (iSPR) as a tool in the characterization of surfaces with laterally varying properties. Within the scope of this work, an instrument for iSPR analysis was designed and built. LÄS MER

  2. 2. Miniaturized localized surface plasmon resonance biosensors

    Författare :Si Chen; Chalmers University of Technology; []
    Nyckelord :colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

    Sammanfattning : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

  4. 4. Mechanistic and morphological studies of Aβ amyloid formation using surface plasmon resonance

    Författare :Md Tohidul Islam; Anders Olofsson; Ludmilla Morozova-Roche; Vytautas Smirnovas; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; medicinal chemistry; läkemedelskemi; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Alzheimer’s disease (AD) is the most common form of dementia and apart from the individual suffering AD also causes a large economic burden for society. AD is associated with progressive neurodegeneration and atrophy of the brain. LÄS MER

  5. 5. Fragment Based Drug Discovery with Surface Plasmon Resonance Technology

    Författare :Helena Nordström; Helena Danielson; Gregg Siegal; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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
