6. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing
Sammanfattning : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.

7. Operando Single Particle Catalysis - Combining a Nanoreactor and Plasmonic Nanospectroscopy
Sammanfattning : Heterogeneous catalysis is an important cornerstone of modern society with strong ties to the development of sustainable sources of energy and products. Catalysts are typically realized as supported metal nanoparticles that offer active sites that can accelerate chemical reactions by providing energetically more favorable reaction paths. LÄS MER
8. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing
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
9. Plasmonic Nanospectrocopy of Individual Nanoparticles - Studies of Metal-Hydrogen Interactions and Catalysis
Sammanfattning : Localized surface plasmon resonance (LSPR) is the phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light used for the excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. LÄS MER
