1. 11. Concentration measurements in single particle microscopy

   Författare :Magnus Röding; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; fluorescence microscopy; nanoparticle characterization; number concentration; optical wide-field microscopy; single particle tracking; Smoluchowski process; diffusion;

   Sammanfattning : The topic of this thesis is the introduction of two novel methods for using single particle microscopy as a tool for absolute number concentration measurements of Brownian particles. The key idea of both methods is that in order to estimate number concentration, the size of the (three-dimensional) particle detection region has to be estimated. LÄS MER

3. 12. Adapting Deep Learning for Microscopy: Interaction, Application, and Validation

   Författare :Ankit Gupta; Carolina Wählby; Ida-Maria Sintorn; Ola Spjuth; Andreas Hellander; Philip Kollmannsberger; Uppsala universitet; []

   Författare :Göran Johansson; KTH; []
   Nyckelord :x-ray; multilayer; optics; microscopy;

   Sammanfattning : This thesis describes thedevelopment of soft x-ray reflective optics and instrumentationfor compact soft x-ray microscopy. This microscope operates atthe wavelength 3.374 nm in the water-window (2.3 - 4. LÄS MER

5. 14. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

   Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biological Physics; Biologisk fysik;

   Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER

7. 15. Computer Assisted Video Microscopy : in Characterization of Capillary Ensembles

   Författare :Claes Asker; Linköpings universitet; []
   Nyckelord :computer assisted video microscopy; capillary loops; capillary ensembles; skin microcirculation; triangulation; nearest neighbour; MEDICINE;

   Sammanfattning : This thesis focuses on evaluation and analysis of capillary microcirculatory changes in the skin, that can be improved and extended by computer assisted video microscopy. Capillary microscopy has been used extensively, both in clinical practice and research, to study different phenomena in the microvasculature of the skin, mainly in the nailfold of fingers and toes where a large portion of the capillary loop can be observed.
