  1. 11. Single-Molecule Detection and Optical Scanning in Miniaturized Formats

    Författare :Jonas Melin; Fredrik Nikolajeff; Mats Nilsson; Hugh Fan; Uppsala universitet; []
    Nyckelord :Biotechnology; microfluidics; single-molecule detection; MOEMS; μTAS; lab-on-a-chip; RCA; thermoplastics; injection molding; hot embossing; Bioteknik;

    Sammanfattning : In later years polymer replication techniques have become a frequently employed fabrication method for microfluidic and micro-optical devices. This thesis describes applications and further developments of microstructures replicated in polymer materials. LÄS MER

  3. 12. Förster Resonance Energy Transfer - from single molecule spectroscopy to imaging

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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.

  5. 14. How precise is cyclic life? : Insights during a single molecule revolution of the bacterial cell cycle

    Författare :Mats Walldén; Johan Elf; Peter Graumann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E.coli; cell cycle; replication initiation; transcription factor; gene-regulation; single molecule microscopy; microfluidics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Bacterial cells reproduce by doubling in size and dividing. The molecular control systems which regulate the cell cycle must do so in a manner which maintains a similar cell size over many generations. A cell can under conditions of fast growth conclude cell cycles in shorter time than the time required to replicate its chromosome. LÄS MER
