  1. 6. Fluorescence correlation spectroscopy, photophysical aspects and applications

    Författare :Jerker Widengren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Fluorescence correlation spectroscopy (FCS) is a technique where dynamic processes on the molecular level are studied by the use of fluorescence. The molecules are excited within a focused stationary laser beam and the resulting fluorescence fluctuations are analyzed in the form of an autocorrelation function. LÄS MER

  3. 7. Development and application of ultra-sensitive fluorescence spectroscopy and microscopy for biomolecular interaction studies

    Författare :Lei Xu; Jerker Widengren; Gerhard Schütz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single molecule spectroscopy; fluorescence correlation spectroscopy; stimulated emission microscopy; cancer; biomolecular interaction; co-localization; Biological Physics; Biologisk fysik;

    Sammanfattning : This thesis describes the development of sensitive and high-resolution fluorescence spectroscopic and microscopic techniques and their application to probe biomolecules and their interactions in solution, lipid membrane model systems and in cells. Paper I-IV are largely focused on methodological developments. LÄS MER

  4. 8. Correlation spectroscopy of single emitters : fundamental studies and applications

    Författare :Hans Blom; KTH; []
    Nyckelord :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

  5. 9. New applications of fluorescence spectroscopy for monitoring drinking water disinfection and distribution

    Författare :Masoumeh Heibati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; UV disinfection; Fluorescence spectroscopy; drinking water; distribution network;

    Sammanfattning : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants and within distribution networks. LÄS MER

  7. 10. The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k

    Författare :Karin Julenius; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface plasmon resonance; fluorescence spectroscopy; circular dichroism spectroscopy; NMR spectroscopy; hydrophobic effect; protein stability; dimerization; cooperativity; calcium binding; EGF-module; EF-hand; calbindin D9k; protein S; synthet; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. LÄS MER
