  1. 21. Advancing DNA-based proximity methods

    Författare :Mattias Leino; Ola Söderberg; John Löfblom; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 22. Studies of plasma-facing materials and macromolecules using scanning probe microscopy

    Författare :Nils Almqvist; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Sammanfattning : The main topic of this thesis is experimental analysis of material surfaces using scanning probe microscopies. These microscopes are used for characterization through high-resolution topographical imaging, but also for controlled modification of surfaces and molecules. LÄS MER

  4. 23. Atom Probe Field Ion Microscopy of Surface Zones, Coatings and Interfaces

    Författare :Anders Kvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ag GaAs; ohmiccontact; Au GaAs; Schottky contact; Cu3Au; APFIM; AuGe GaAs; gradient sintering; cemented carbides; CVD;

    Sammanfattning : This thesis is focused on developingmethods for high resolution microanalysis of coatings on a substrate, andsurface zones of a bulk sample using atom probe field ion microscopy,APFIM. The APFIM technique is described and some examples of its applications to semiconductors,cemented carbides and intermetallic compounds are given. LÄS MER

  5. 24. Development and application of advanced electron microscopy techniques for materials in biological systems

    Författare :Pernilla Nevsten; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiple-unit drug; EFTEM; EELS; cyanine dye; SSAT; cryo-TEM; virus; TEM; apoptosis; SEM; AFm; α-TCP; apatite; XEDS; TEM grid; microscopy supports;

    Sammanfattning : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. LÄS MER

  7. 25. Revealing the architecture and composition of the sperm flagellum tip

    Författare :Davide Zabeo; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Structural biology; Microtubules; Electron microscopy; Cryo-electron microscopy; Cryo-electron tomography;

    Sammanfattning : The eukaryotic flagellum is a membrane-bound protruding organelle with a cytoskeleton of microtubules. Flagella are found in unicellular as well as multicellular organisms, performing a variety of functions. LÄS MER
