  2. 2. Advances in Holographic Optical Trapping

    Författare :Martin Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :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

    Författare :Emma Eriksson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :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

  4. 4. KNOW YOUR ENEMY : Characterizing Pathogenic Biomaterials Using Laser Tweezers

    Författare :Tobias Dahlberg; Magnus Andersson; Krister Wiklund; Mikael Sjödahl; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Optical Tweezers; Laser Tweezers; Raman Spectroscopy; Bacterial Adhesion; Biophysics; Pili; Bacterial Spores; Endospores; Oocysts; Cryptosporidium; Optics; biology; biologi; fysik; Physics;

    Sammanfattning : Diseases caused by pathogenic agents such as bacteria and viruses result in devastating costs on personal and societal levels. However, it is not just the emergence of new diseases that is problematic. Antibiotic resistance among bacteria makes uncomplicated infections difficult and lethal. LÄS MER
