17. Plasmonic Nanostructures for Molecular Spectroscopy
Sammanfattning : This thesis focuses on the fabrication, characterization and utilization of nanostructures for chemical sensing and optical enhancement processes.Noble metal nanostructures can support localized surface plasmon resonances (LSPRs), which amplify the strength of the electromagnetic field close to the structures.

18. Excited States of Carotenoids and Their Functions in Light Harvesting
Sammanfattning : The research presented in this thesis is focused on characterization of photophysical properties of lowest singlet excited states of carotenoids and their functions in the process of photosynthetic light harvesting. It is shown that the various light-harvesting complexes utilize different strategies to achieve efficient energy transfer from carotenoids to (bacterio)chlorophylls. LÄS MER
19. Kinetic Recognition of Nucleic Acids - Studies on the DNA Binding Selectivity of Threading Ruthenium Complexes
Sammanfattning : Despite the great progress in our understanding of DNA during the past half-century, there are many important aspects of its chemical and biological role yet to be explored. The principles by which it selectively interacts with other molecules have attracted much interest due to the relevance for fundamental cellular processes, as well as for the development of diagnostic probes and effective pharmaceutical agents.
