  2. 2. Advances in Holographic Optical Trapping

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Martin Persson; Göteborgs universitet.; Gothenburg University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical tweezers; Holographic optical trapping; Optical force measurement; Spatial light modulators; Holographic beam steering; Liquid crystals;

    Sammanfattning : Holographic optical trapping (HOT) is a technique for non-invasive dynamic anipulation of multiple microscopic objects, which has been used for many applications in the life sciences during the past decade. The technique uses holographic beam steering with a spatial light modulator (SLM) to direct light to the desired positions of optical traps. LÄS MER

  3. 3. Towards quantitative single cell analysis using optical tweezers and microfluidics

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Emma Eriksson; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical tweezers; holographic optical tweezers; microfluidics; lab-on-a-chip; fluorescence microscopy; spatial light modulator; single cell analysis; quantitative systems biology; GFP; Saccharomyces cerevisiae;

    Sammanfattning : Experiments on single cells have the potential to uncover information that would not be possible to obtain with traditional biological techniques, which only reflect the average behavior of a population of cells. In the averaging process, information regarding heterogeneity and cellular dynamics, that may give rise to a nondeterministic behavior at the population level, is lost. LÄS MER

  5. 5. Optical Imaging and Spectroscopy of Metal Nanostructures

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Juris Prikulis; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; surface plasmon resonance; surface-enhanced Raman spectroscopy; near-field optical microscopy; optical tweezers;

    Sammanfattning : Noble metal structures with size in the sub 100 nm range exhibit extraordinary optical properties due to collective oscillations of conduction electrons, the surface plasmon resonances (SPR). The most remarkable feature of these structures is the ability to redistribute electromagnetic radiation and concentrate strong fields near the surface. LÄS MER
