16. Nanofluidics as a tool for parallelized single nanoparticle characterization: Fluorescence single nanoparticle catalysis and size determination through 1D Brownian motion
Abstract : Nanoparticles exist widely in nature and are objects of study in many scientific disciplines due to their high performance in a wide range of applications. With modern techniques that facilitate creating and shaping of nanoparticles into ever more complex shapes and compositions, characterization of particle properties is essential. READ MORE

17. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging
Abstract : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

18. Quantitative chemical imaging to study content release from single nanovesicles
Abstract : Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, vesicles can fully or partially release their contents. READ MORE

19. Illumination in single cell optical microscopy studies - friend and foe
Abstract : This thesis focuses on how to use light as a biological stress factor in optical microscopy experiments and simultaneously use the illumination to image the spatial and temporal protein dynamics in single yeast cells. The stress responses to environmental changes other than light have been extensively investigated in budding yeast, Saccharomyces cerevisiae, often using techniques based on population averages.

20. Development of novel bioanalytical assays with single-molecule readout for biomarker detection and drug candidate characterization
Abstract : Bioanalytical assays with single-molecule readout for studying molecular interactions have in the past decades received increasing attention. The high sensitivity often offered by this readout scheme has for example enabled ultra-sensitive analyte detection, having important implications for monitoring early disease progression and the effects of drug treatment.
