Local Viscosity and Environment on the Nanometer Scale
New optical setup for two photon excitation time-resolved fluorescence anisotropy and lifetime measurements was built and used to understand the local environment and viscosity. The rotational correlation time constants by the fluorescence anisotropy provide the information on the hydrodynamic …

Rapid diffusion in the brain extracellular space - biophysical constraints and physiological implications
… hippocampal neuropil (area CA1). Next, we adopt time‐resolved fluorescence anisotropy imaging microscopy to establish the previously unknown instantaneous diffusivity of small molecules in the extracellular space. The result indicates that nanometer‐scale diffusivity in the brain extracellular …

Advanced Fluorescence Lifetime Imaging and Spectroscopy Techniques for Biological Samples
… and chemical signalling. In this thesis, fluorescence-based studies were conducted on a fluorescent molecular rotor, BODIPY-Ci2, which was used to measure the intracellular viscosity. BODIPY-C12 is insensitive to the surrounding polarity using solvatochromic methods. It was demonstrated …

Investigation of the dynamics and conformational changes of the U1A protein
… essential helix in the U1A protein, helix C. The time-resolved anisotropy data obtained here supports the induced fit mechanism of binding. Chapter 3 describes the kinetic studies of dissociation of the U1A-SL2 RNA complex using laser T-jump and stopped-flow fluorescence methods. Analysis of the …
