  2. 1. Tailoring Fluorescent Probes for Organelle-Specific Imaging and Sensing

    Author : Xin Zhang; Zhangjun Hu; Kajsa Uvdal; Fredrik Almquist; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fluorescent imaging; Ratiometric Nanoprobe; Autophagy; Apoptosis; FRET; Fluorescerande avbildning; Ratiometric Nanoprobe; Autophagy; Apoptosis; FRET;

    Abstract : Exploring and visualizing biological and pathological processes in living cells are useful for both fundamental research and applications. An understanding on the molecular level for these processes with focus on tracking biomarkers, collecting information about their surroundings, and uncovering essential molecular pathways and functions in live cells are of vital interest for cell biological study and clinical diagnosis application.

  4. 2. 3D super-resolution microscopy of living cells using reversibly switchable fluorophores

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

    Abstract : 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. READ MORE

  5. 3. Preclinical X-Ray Fluorescence Imaging with Multifunctional Nanoparticles

    Author : Giovanni Marco Saladino; Hans Hertz; Muhammet Toprak; Stefan Andersson-Engels; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Abstract : X-ray fluorescence imaging (XFI) is an emerging technique for preclinical studies, characterized by high resolution, specificity, and sensitivity. It relies on nanoparticles (NPs) as contrast agents, which must be constituted of specific elements that match the X-ray source energy for detection. READ MORE

  6. 4. Radioluminescence : A simple model for fluorescent layers - analysis and applications

    Author : Jan Lindström; Åsa Carlsson Tedgren; Eva Lund; Michael Sandborg; Ioannis Kandarakis; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : A phosphor or scintillator is a material that will emit visible light when struck by ionising radiation. In the early days of diagnostic radiology, it was discovered that the radiation dose needed to get an image on a film, could be greatly reduced by inserting a fluorescent layer of a phosphor in direct contact with the film.

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

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

    Abstract : 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.
