  2. 1. Biomolecular interactions at model interfaces : a self-assembled monolayer approach

    Author : Sofia Svedhem; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The overall aim of this thesis has been to explore the use of self-assembled monolayers (SAMs) in model studies of biomolecular binding at interfaces. Molecular details of interfaces are difficult to address experimentally, and in spite of the fact that interactions in the living system commonly occur at interfaces, e.g. READ MORE

  4. 2. Characterization of Self-Assembled Monolayers of Oligo(phenyleneethynylene) Derivatives on Gold

    Author : Somsakul Watcharinyanon; Lars Johannson; Ellen Moons; Stacey Sorensen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-assembled monolayers; Oligo phenyleneethynylene ; high-resolution X-ray photoemission spectroscopy HRXPS ; near-edge X-ray absorption fine structure spectroscopy NEXAFS ; Material physics with surface physics; Materialfysik med ytfysik; Physics; Fysik;

    Abstract : Oligo(phenyleneethynylene) (OPE) molecules are a class of fully conjugated aromatic molecules, that attract attention for their application as “molecular wires” in molecular electronic devices. In this thesis work, self-assembled monolayers (SAMs) formed from a variety of OPE derivatives have been studied. READ MORE

  5. 3. Particle interactions at the nanoscale : From colloidal processing to self-assembled arrays

    Author : Bertrand Faure; Lennart Bergström; Albert Philipse; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; Materials Chemistry; materialkemi;

    Abstract : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. READ MORE

  6. 4. Densities and Sizes of Self-assembled Quantum Dots Grown by MOVPE

    Author : Jonas Johansson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembled quantum dots; Metal organic vapour phase epitaxy; Physics; Stranski-Krastanow; Fysicumarkivet 2000:Johansson; Halvledarfysik; Semiconductory physics; Fysik;

    Abstract : This thesis is based on results concerning the formation of semiconductor self-assembled quantum dots. The quantum dots have been grown by metal organic vapour phase epitaxy in the Stranski-Krastanow growth mode. READ MORE

  7. 5. Synthesis of Orthogonally Functionalized Oligosaccharides for Self-assembled Monolayers and as Multimodal Tools in Chemical Biology

    Author : Timmy Fyrner; Peter Konradsson; Stefan Svensson; Bo Liedberg; Ulf Ellervik; Linköpings universitet; []
    Keywords : Oligosaccharide synthesis; glycosylation; thioglycosides; orthogonally protected; oligo lactosides ; spacer molecule; heterobifunctional; surface plasmon resonance; lipid anchor; self-assembled monolayers; glyconanoparticles;

    Abstract : This thesis covers different topics in the field of synthetic organic chemistry combined with the field of surface science and glycobiology.First, the text presents a series of orthogonally protected oligosaccharides (tri-, penta-, and heptasaccharides) of varying length and structures, which are synthesized with the aim of developing novel heterobifunctional biocompatible cross-linkers.
