  2. 1. Towards quantitative single cell analysis using optical tweezers and microfluidics

    Author : Emma Eriksson; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Development of quantitative optical microscopy methods for single cell analysis

    Author : Katarina Logg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein localization; quantitative optical microscopy; live cell imaging; image analysis; cellular stress;

    Abstract : Optical microscopy has brought powerful methods to biological research, in particular the possibility to assay dynamic molecular processes within living individual cells. This thesis deals with various aspects of fluorescence and Raman microscopy, such as the possibility of avoiding cellular damage or stress caused by illumination, how to manipulate single cells for spectroscopic analysis and how to quantify images automatically.

  5. 3. Quantitative image analysis : a focus on automated characterization of structures in optical microscopy of iron ore pellets

    Author : Frida Nellros; Carolina Wählby; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : Sintering occurs in many types of material such as iron, ceramics and snow, typically during thermal treatment, and aects the material properties, particularly the strength, by the bonding of particles into a coherent structure. In order to improve the mechanical strength in magnetite iron ore pellets it is important to be able to characterize and quantitatively measure the degree of sintering and features that impact the process of sintering.

  6. 4. Laboratory soft x-ray microscopy and tomography

    Author : Michael Bertilson; Hans Hertz; Gerd Schneider; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; Diffractive optics; Zone plates; X-ray microscopy; Soft X-ray physics; Tomography; Optics; Optik; Physics; Fysik;

    Abstract : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. READ MORE

  7. 5. Bridging Single-Particle Characterisation Gaps of Optical Microscopy in the Nano-Submicron Regime

    Author : Erik Olsén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; holography; particle shape; dynamics; Optical microscopy; particle tracking; size estimation; iSCAT; material sensitivity;

    Abstract : As the practical importance of particles in the nano-submicron size regime continues to increase in both biomedical applications and industrial processes, so does the need for accurate and versatile characterisation methods. Optical scattering microscopy methods are commonly used for single-particle characterisation as they provide quick measurements at physiologically relevant conditions with detection limits reaching down to individual biomolecules.
