  2. 1. Concentration measurements in single particle microscopy

    Author : Magnus Röding; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; fluorescence microscopy; nanoparticle characterization; number concentration; optical wide-field microscopy; single particle tracking; Smoluchowski process; diffusion;

    Abstract : The topic of this thesis is the introduction of two novel methods for using single particle microscopy as a tool for absolute number concentration measurements of Brownian particles. The key idea of both methods is that in order to estimate number concentration, the size of the (three-dimensional) particle detection region has to be estimated. READ MORE

  4. 2. Raster Image Analysis of Diffusion via Single Particle Methods

    Author : Marco Longfils; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; single particle tracking; raster scan; confocal laser scanning microscopy; image correlation spectroscopy; raster scan;

    Abstract : Soft biomaterials are widely used in many application areas, spanning from packaging materials to pharmaceuticals. To enhance their functionalities, understanding the interplay between microstructure and mass transport properties in these materials is fundamental. READ MORE

  5. 3. Protein structure dynamics and interplay : by single-particle electron microscopy

    Author : Hans Elmlund; Hans Hebert; José Maria Carazo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biophysics; biochemistry; molecular; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : Single-particle cryo-electron microscopy (cryo-EM) is a method capable of obtaining information about the structural organization and dynamics of large macromolecular assemblies. In the late nineties, the method was suggested to have the potential of generating “atomic resolution” reconstructions of particles above a certain mass. READ MORE

  6. 4. Combining Nanoplasmonics and Nanofluidics for Single Particle Catalysis

    Author : David Albinsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; heterogeneous catalysis; CO oxidation; plasmonic sensing; dark field scattering spectroscopy; nanocatalyst; LSPR; single particle catalysis; nanofluidics; nanoreactor; Cu oxidation;

    Abstract : Nanoparticles are, due to their large exposed surface area, widely used in the field of heterogeneous catalysis where they accelerate and steer chemical reactions. Although catalysis has been known about for centuries, the scrutiny of catalysts under realistic application conditions is still a major challenge. READ MORE

  7. 5. Biological Insights from Single-Particle Tracking in Living Cells

    Author : Arash Sanamrad; Johan Elf; Måns Ehrenberg; Achillefs Kapanidis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single-particle tracking; intracellular diffusion; nucleoid exclusion; transcription-translation coupling; antibiotics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : Single-particle tracking is a technique that allows for quantitative analysis of the localization and movement of particles. In this technique, trajectories are constructed by determining and connecting the positions of individual particles from consecutive images. READ MORE
