  2. 1. Advancing DNA-based proximity methods

    Author : Mattias Leino; Ola Söderberg; John Löfblom; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in situ; proximity dependent intiation of hybridization chain reaction; hybridization chain reaction; Oligonucleotide design; proximity ligation assay; protein interaction; microscopy; purification; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : Cellular functions are governed by intricate chains of interactions between proteins. In order to properly understand cellular biology one must look into, not only protein function, but also its interacting network. READ MORE

  4. 2. Dermal cell trafficking : from microscopy to microdialysis

    Author : Florence Sjögren; Magnus Lindberg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The term dermal cell trafficking has been used to describe the dynamic nature of cell movement in the dermis reflecting the skin's role as an immunological organ. A light microscopic experimental model for qualitative and quantitative counting of the dermal inflammatory cell infiltrate in allergic, acute irritant and cumulative irritant contact reactions has been developed In human studies use of microdialysis technique has enabled observation of biochemical events in the skin, in vivo over a period of time.

  5. 3. Theoretical modeling of scanning tunneling microscopy

    Author : Alexander Gustafsson; Magnus Paulsson; Jorge Iribas Cerdá; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scanning tunneling microscopy; Computational models; Quantum tunneling; Green s functions; Density functional theory; Condensed Matter Physics; Kondenserade materians fysik;

    Abstract : The main body of this thesis describes how to calculate scanning tunneling microscopy (STM) images from first-principles methods. The theory is based on localized orbital density functional theory (DFT), whose limitations for large-vacuum STM models are resolved by propagating localized-basis wave functions close to the surface into the vacuum region in real space.

  6. 4. Nanofluidic Scattering Microscopy for Single Particle Catalysis

    Author : Björn Altenburger; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; label-free methods; Platinum; Nanofluidics; Single nanoparticle catalysis; Particle trapping; Hydrogen Peroxide decomposition; Colloidal particles; Dark field microscopy;

    Abstract : Heterogeneous catalysis concerns material formulations – catalysts – that can assist a chemical reaction by improving its rate or selectivity, by lowering activation barriers and altering the energy landscape. The core of catalysts are often tiny metal particles that provide a large reaction surface at a small volume, as well as low coordination sites whose type and abundance depends on particle size and shape.

  7. 5. Modeling of non-equilibrium scanning probe microscopy

    Author : Alexander Gustafsson; Magnus Paulsson; Tchavdar Todorov; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scanning tunneling microscopy; molecular dynamics; density functional theory; non-equilibrium Green s functions; Condensed Matter Physics; Kondenserade materians fysik;

    Abstract : The work in this thesis is basically divided into two related but separate investigations.The first part treats simple chemical reactions of adsorbate molecules on metallic surfaces, induced by means of a scanning tunneling probe (STM). The investigation serves as a parameter free extension to existing theories. READ MORE
