  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. Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles

    Detta är en avhandling från Umeå : Fysik

    Författare :Magnus Andersson; Umeå universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical tweezers; biological physics; unfolding; Escherichia coli; force measurements; energy landscape; dynamic force spectroscopy; manipulation; polymers; pili; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused light. The technique has therefore become a powerful tool in the field of biophysics. LÄS MER
