21. Transient State Fluorescence Microscopy - method development and biological applications : Exploiting the dark states of fluorophores to measure oxygen concentrations, redox state, Förster resonance energy transfer and membrane viscosity
Sammanfattning : Due to their long lifetime, triplet, redox and other transient states of fluorophores are highly sensitive to the micro-environment. Imaging their spatial distribution in biological samples can therefore help answer interesting questions about the metabolism, molecular interactions and dynamics in living cells. LÄS MER
22. Imaging and Spectroscopic Mapping of Blood Cell Activity : Nanoparticles and Neutrophil Extracellular Traps
Sammanfattning : Imaging and visualization of cell activity when exposed to nanomaterial are of main importance, when investigating biological response to a wide range of biomaterials from medical implants to smart nanoprobes. The ability to provide molecular and chemical information with spatial resolution in the region of sub-µm leads to increased insight and understanding of these biological challenges. LÄS MER
23. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation
Sammanfattning : Combustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. LÄS MER
24. Multiphoton Microscopy Targeting Tissue Development. Towards the real-time imaging of epidermal differentiation
Sammanfattning : The development of novel organ-on-a-chip models calls for methodologies, which will allow the study of tissue development and pharmacological outcome in real-time. Multiphoton microscopy (MPM) has been proposed as a suitable technique for noninvasive imaging of live specimens, utilizing intrinsic tissue fluorescence. LÄS MER
25. Time-Varying Excitation in Fluorescence Spectroscopy for Biological Applications
Sammanfattning : The focus of this thesis is to explore and use the benefits of time-varying excitation in fluorescence spectroscopy for studies of biomolecular dynamics. Two new techniques taking advantage of modulated excitation are presented. LÄS MER
