1. 6. Molecular Processes in Dynamic Wetting : Du som saknar dator/datorvana kan kontakta Cathrine Bergh, [email protected] för information

   Författare :Petter Johansson; Berk Hess; Erik Lindahl; Guillaume Galliero; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contact lines; nanodroplets; computational physics; molecular dynamics; fluid dynamics; multi-phase flows; electrowetting; Biologisk fysik; Biological Physics;

   Sammanfattning : The spreading of liquids onto and over surfaces is a fundamental process in nature. It is present in all forms and sizes: From rivers carving through landscapes, to our blood stream transporting nutrients to cells, and even single water molecules moving through channels into these cells.

3. 7. Fluorescence-based Transient State Monitoring for biomolecular, cellular and label-free studies

   Författare :Johan Tornmalm; Jerker Widengren; Maria Garcia Parajo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological Physics; Biologisk fysik; Fysik; Physics;

   Sammanfattning : Fluorophore blinking dynamics are highly sensitive to the local environment and can be used as an additional readout parameter to increase the information gained from existing fluorescence techniques.The origin of these blinking patterns are photophysical transitions to and from a manifold of non-luminescent states.

4. 8. Time-Resolved Optical Properties of Colloidal CdSe-CdS/ZnS Core-Multishell Quantum Dots in Bioimaging

   Författare :Li Li; Ying Fu; Rajeev Ahuja; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological Physics; Biologisk fysik;

   Sammanfattning : Semiconductor quantum dots (QDs) have attracted great attention as a novel fluorescent material in the last twenty years. Their superior optical properties such as high brightness and photostability, broad absorption spectrum, narrow and size-tunable emission spectrum, enable them great application in bioimaging.

5. 9. Super resolution optical imaging – image analysis, multicolor development and biological applications

   Författare :Daniel Rönnlund; Jerker Widengren; Christian Eggeling; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stimulated emission depletion STED microscopy; nanoscopy; multicolor; image analysis; diagnostics; cancer; metastasis; Biological Physics; Biologisk fysik;

   Sammanfattning : This thesis focuses on super resolution STED optical imaging. STED provides a wealth of new informational content to the acquired images by using stimulated emission to surpass the diffraction limit in optical fluorescence microscopy. LÄS MER

7. 10. 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
