  2. 1. Two-Photon Excited Fluorescence Depolarisation : Experimental and Theoretical Development

    Author : Linus Ryderfors; Emad Mukhtar; Lennart B.-Å. Johansson; Yehudi K. Levine; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-photon excitation; Fluorescence; Fluorescence depolarisation; Fluorescence anisotropy; Time-correlated single photon counting; Gold nanoparticles; Rotational diffusion; Excited state symmetry; Extended Förster theory; Orientation correlation functions; Donor-donor energy migration DDEM ; Chemical physics; Kemisk fysik;

    Abstract : We have studied fundamental aspects of time-resolved two-photon excited fluorescence depolarisation. The thesis presents experimental as well as theoretical progress. READ MORE

  4. 2. Studies on the remineralization of white spot lesions : longitudinal assessment with quantitative light-induced fluorescence

    Author : Susan Al-Khateeb; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The global aim of this work was to develop and test the light induced fluorescence method using either laser light or a regular, i.e. noncoherent light source for quantification of mineral changes in white spot lesions. Validation studies were carried out to establish the correlation between fluorescence loss and mineral loss. READ MORE

  5. 3. Towards Quantitative Diagnostics using Short-Pulse Laser Techniques

    Author : Andreas Ehn; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PicoSecond Laser Diagnostics; Raman Scattering; Photo Fragmentation; Fluorescnece Lifetime Imaging; Temporal Filtering; Fysicumarkivet A:2012:Ehn; LIDAR; Laser-Induced Fluorescence;

    Abstract : Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena that affects the research of interest.

  6. 4. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Author : Kristofer Bodvard; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Abstract : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. READ MORE

  7. 5. On Multidimensional Dynamic Fluorescence Imaging and Quantitative Image Analysis in Wide-Field Microscopy Applications to Studies of Astroglial Cells

    Author : Siamak Khatibi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volume estimation; astrocyte; calcium wave; intercellular signaling; volumetric image analysis; fluorescence imaging; three-dimensional 3D reconstruction; segmentation;

    Abstract : Modern biological research has benefited from a renaissance in light microscopy, brought about by the convergence of developments in fields as diverse as electronics, optics, molecular biology, computer science, and reagent chemistry. Integration of these has transformed microscopy into a highly useful, dynamic research tool for biology and medicine. READ MORE
