  2. 1. Single molecule dynamics

    Author : Lars Edman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Properties found in an ensemble of molecules may not be understood if it is not possible to study each molecule one by one. This thesis is concerned with the study of the dynamic properties of individual complex biological molecules as observed by confocal single-molecule fluorescence spectroscopy. READ MORE

  4. 2. Single-­molecule spectroscopy of π-­conjugated polymers

    Author : Oleg Mirzov; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence lifetime; low temperature; spectral diffusion; blinking; MEH-PPV; Single-molecule spectroscopy; π-conjugated polymers; 2D polarization; Monte Carlo; energy transfer;

    Abstract : When applied to condensed-matter samples of large organic molecules, optical spectroscopy faces the problem of inhomogeneous broadening caused by the diversity of environments and conformations that sample molecules are subjected to. This severely limits the information that can be extracted from optical spectra. READ MORE

  5. 3. Overstretching short DNA – Single-molecule force spectroscopy studies

    Author : Niklas Bosaeus; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA stretching; mechanical properties of DNA; single molecule; optical tweezers; DNA structure;

    Abstract : Structural deformation of DNA has a central role in many biological processes. It occurs, for example, during replication, transcription, and regulation of the activity of the genome. To understand these fundamental processes it is necessary to have a detailed knowledge of the mechanical properties of DNA. READ MORE

  6. 4. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging

    Author : Rafael Camacho Dejay; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Energy transfer; Single molecule spectroscopy; Exciton; Fluorescence microscopy; Fluorescence polarization; Light-harvesting; Chromophore; Conjugated Polymer; Photosynthesis;

    Abstract : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

  7. 5. Förster Resonance Energy Transfer - from single molecule spectroscopy to imaging

    Author : Evangelos Sisamakis; Jerker Widengren; Paul R Selvin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FRET; FCS; single-molecule biophysics;

    Abstract : During the last fifteen years several methods have been developed for probing biomolecules (DNA, RNA, proteins) one at a time. Among these methods fluorescence spectroscopy and in particular its many implementations for monitoring Förster Resonance Energy Transfer (FRET), have attracted much interest. READ MORE
