1. Two-Photon Excited Fluorescence Depolarisation : Experimental and Theoretical Development
Sammanfattning : We have studied fundamental aspects of time-resolved two-photon excited fluorescence depolarisation. The thesis presents experimental as well as theoretical progress. LÄS MER
2. Fluorescence studies of complex systems : organisation of biomolecules
Sammanfattning : The homo and hetero dimerisation of two spectroscopically different chromophores were studied, namely: 4,4-difluoro-4-bora-3a,4a-diazas-indacene (g-BODIPY) and its 5-styryl-derivative (r-BODIPY). Various spectroscopic properties of the r-BODIPY in different common solvents were determined. LÄS MER
3. Dynamics of Enzyme Immobilization in Mesoporous Silica Particles
Sammanfattning : The focus of this thesis is placed on the dynamic behavior of proteins in confining environments which is studied as a scientific challenge for a deeper understanding of the immobilization mechanism and a better designing of enzyme immobilization in porous materials. Enzymes are immobilized in porous materials to improve the enzyme activity and simplify their purification from the product solution in biocatalytic applications. LÄS MER
4. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes
Sammanfattning : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. LÄS MER
5. Light polarization in single molecule spectroscopy: From visualization of structural anisotropy and energy transfer to super-resolution imaging with orientational contrast
Sammanfattning : Π-conjugated polymers are an important class of materials which can be used in e.g. photoelectric (solar cells) or electroluminescent (displays) devices. These materials are implemented in a number of applications these days since a lot is already known about them. LÄS MER
