1. 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
Abstract : 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. READ MORE

2. Monitoring Proton Exchange and Triplet States with Fluorescence
Abstract : Fluorescent molecules commonly shift to transient dark states, induced bylight or triggered by chemical reactions. The transient dark states can beused as probes of the local environment surrounding the fluorescent molecules,and are therefore attractive for use in biomolecular applications. READ MORE

3. Photo-induced dark states influorescence spectroscopy – investigations & applications
Abstract : This thesis focuses on investigations of transient dark states of fluorescentmolecules using spectroscopic techniques. The main purpose is to show andconvince the reader that transient dark states are not always a nuisance, butalso represent an additional source of information. READ MORE

4. Synthesis and development of compounds for nonlinear absorption of light
Abstract : High-intensity light — for instance that from a laser — can be destructive, not only to the human eye, but also to equipment such as imaging sensors and optical communication devices. Therefore, effective protection against such light is desirable. READ MORE

5. Temporal Modulation in Fluorescence Spectroscopy and Imaging for Biological Applications
Abstract : This thesis explores the benefits of intensity modulation for the purpose of extending the range of applications of fluorescence spectroscopy and imaging in cellular and molecular biology and medicine. Long-lived transient states of fluorescent molecules can, because of their long lifetimes, be used to detect subtle changes in the microenvironment of the molecule. READ MORE
