  1. 21. Optical spectroscopy in biomedicine - detection of embedded inclusions and in vivo pharmacokinetics

    Författare :Jenny Svensson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temperature; Atomic and molecular physics; Atom- och molekylärfysik; photosensitizer; photodynamic therapy; fluorescence spectroscopy; multispectral imaging;

    Sammanfattning : The main theme of this thesis is the use of fluorescence spectroscopy in biomedicine. The work presented in the thesis can be divided into three areas of applications. The first area involves the use of fluorescence to find the location of a deeply situated fluorophore within turbid media. LÄS MER

  3. 22. 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

  4. 23. Transient State Fluorescence Microscopy - method development and biological applications : Exploiting the dark states of fluorophores to measure oxygen concentrations, redox state, Förster resonance energy transfer and membrane viscosity

    Författare :Thiemo Spielmann; Jerker Widengren; Karsten König; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transient States imaging TRAST ; Triplet State imaging; fluorescence microscopy; modulated excitation; triplet state; radical state; trans-cis isomerisation;

    Sammanfattning : Due to their long lifetime, triplet, redox and other transient states of fluorophores are highly sensitive to the micro-environment. Imaging their spatial distribution in biological samples can therefore help answer interesting questions about the metabolism, molecular interactions and dynamics in living cells. LÄS MER

  5. 24. Correlation spectrosopy of single emitters : fundamental studies and applications related to quantum optics and life science

    Författare :Hans Blom; KTH; []
    Nyckelord :optics; analytical chemistry; solid states; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Correlation analysis and correlation spectroscopy has eversince the first developments, to characterise light emittingprocesses and biomolecular dynamics, continued to extend itspractical applicability. Today, correlation spectroscopy can beused in life science to study dynamical processes even at thesingle molecule level. LÄS MER

  7. 25. New innovative methods for non-intrusive optical diagnostics of high-voltage insulator materials
