  1. 1. Super resolution fluorescence imaging : analyses, simulations and applications

    Författare :Jan Bergstrand; Jerker Widengren; Eilon Sherman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Fluorescence methods offer extraordinary sensitivity and specificity, and are extensively used in the life sciences. In recent years, super resolution fluorescence imaging techniques have developed strongly, uniquely combining ~10 nm sub diffraction resolution and specific labeling with high efficiency. LÄS MER

  3. 2. High-resolution imaging of kidney tissue samples

    Författare :David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biological Physics; Biologisk fysik;

    Sammanfattning : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  4. 3. 3D super-resolution microscopy of living cells using reversibly switchable fluorophores

    Författare :Andreas Bodén; Ilaria Testa; Francisco Balzarotti; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RESOLFT; 3D imaging; super-resolution; microscopy; reversibly switchable fluorescent proteins; Biological Physics; Biologisk fysik;

    Sammanfattning : Traditional optical microscopy techniques are limited in spatial resolution due to the wave nature of light. This means that neighboring objects separated by a distance smaller than about 200 nm cannot be distinguished. LÄS MER

  5. 4. Imaging Living Cells with an X-ray Laser

    Författare :Gijs van der Schot; Tomas Ekeberg; Janos Hajdu; Filipe Maia; Pierre Thibault; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coherent diffractive X-ray imaging; flash X-ray imaging; lensless imaging; single particle imaging; cyanobacteria; phasing; image classification; substrate-free sample delivery; X-ray free-electron laser; XFEL; FEL; CDXI; CDI; CXI; FXI; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Sammanfattning : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. LÄS MER

  7. 5. Automated super-resolution microscopy for high-throughput imaging

    Författare :Xavier Casas Moreno; Ilaria Testa; Florian Jug; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RESOLFT; throughput; microscopy automation; nanoscopy; Biologisk fysik; Biological Physics;

    Sammanfattning : Fluorescence microscopes enable the visualization of biological samples with high contrast by labeling specific structures with fluorescent molecules. However, the spatial resolution of widely used microscopy techniques, such as widefield and confocal microscopy, is limited by the size of a focused spot of light, which roughly corresponds to half the wavelength of the illumination.
