  3. 2. Photo-induced dark states influorescence spectroscopy – investigations & applications

    Författare :Andriy Chmyrov; Jerker Widengren; Johan Hofkens; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence correlation spectroscopy; triplet state; isomerisation; photobleaching; quenching; diffusion; total internal reflection; interface; Spectroscopy; Spektroskopi;

    Sammanfattning : This thesis focuses on investigations of transient dark states of fluorescentmolecules using spectroscopic techniques. The main purpose is to show andconvince the reader that transient dark states are not always a nuisance, butalso represent an additional source of information. LÄS MER

  4. 3. Molecular electronic,  vibrational and rotational motion in optical and x-ray fields

    Författare :Sergey Gavrilyuk; Faris Gelmukhanov; Stephane Carniato; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray; nonlinear optics; photobleaching; recoil; anisotropy; Auger; Chemical physics; Kemisk fysik;

    Sammanfattning : The subject of this theoretical  study is the role ofelectronic structure as well as of rotational and vibrational motionson interactions between molecules and electromagnetic radiation,ranging from optical to x-ray. The thesis concerns both linear and nonlinear regimes of the light-matter interaction. LÄS MER

  5. 4. Properties and Applications of Shear-Driven Lipid Bilayers

    Författare :Peter Jönsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photobleaching; cell membrane; simulations; fluorescence microscopy; microfluidics; diffusivity; membrane proteins; lipid bilayer; mobility; model systems;

    Sammanfattning : A supported lipid bilayer (SLB) is a lipid bilayer formed on a solid substrate. This system is currently one of the most common model systems used to imitate the properties of the cell membrane that surrounds human cells. LÄS MER

  7. 5. Structure and dynamics of epithelial cells : Studied with confocal microscopy and flourescence recovery after photobleaching

    Författare :Kajsa Holmgren-Peterson; Annika Scheynius; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Epithelial cells of the human body form a physical barrier to harmful agents and potential invading microorganisms. In the small intestine they must also produce enzymes for digestion of food and be able to absorb nutrients. LÄS MER
