1. 1. Surface Plasmon Resonance : Sensitivity and Resolution

   Författare :Knut Johansen; Günter Gauglitz; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. LÄS MER

3. 2. Imaging surface plasmon resonance

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

4. 3. Miniaturized localized surface plasmon resonance biosensors

   Författare :Si Chen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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.

5. 4. Photochemical Surface Functionalization : Synthesis, Nanochemistry and Glycobiological Studies

   Författare :Lingquan Deng; Olof Ramström; Javier Rojo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Glycobiology; Carbohydrate-protein interactions; Perfluorophenylazide PFPA ; Photochemistry; Carbohydrate surface immobilization; Carbohydrate microarrays; Surface plasmon resonance SPR ; Quartz crystal microbalance QCM ; Atomic force microscopy AFM ; Glyconanomaterials; Concanavalin A Con A ; Cyanovirin-N CV-N ; 1-Glycosyl thiols; Mutarotation; 1-S-glycosylation; Stereocontrol;

   Sammanfattning : This thesis mainly deals with the development of photochemical approaches to immobilize carbohydrates on surfaces for glycobiological studies. These approaches have been incorporated into a number of state-of-the-art nanobio-platforms, including carbohydrate microarrays, surface plasmon resonance (SPR), quartz crystal microbalance (QCM), atomic force microscopy (AFM), and glyconanomaterials.

7. 5. Macromolecules at Interfaces

   Författare :Helén Larsericsdotter; Sven Oscarsson; Jos Buijs; Willem Norde; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein; Adsorption; Immobilization; Surface; Surface Plasmon Resonance; SPR; Mass Spectrometry; MS; Differential Scanning Calorimetry; DSC; FT ICR; Lysozyme; Bovine Serum Albumin; BSA; Myoglobin; Globular; Kemi; Chemistry; Kemi;

   Sammanfattning : In this thesis, the structure and stability of globular proteins adsorbed onto nanometer-sized hydrophilic silica particles were investigated using differential scanning calorimetry (DSC), hydrogen/deuterium exchange (HDX), and mass spectrometry (MS). The adsorption process itself was characterized with fluorescence and absorption spectroscopy and surface plasmon resonance (SPR). LÄS MER
