  2. 1. 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

  4. 2. Stimuli-responsive lipid bilayer mimics for protein, virus and cell recognition

    Author : Sing Yee Yeung; Malmö universitet; []
    Keywords : Lipid bilayers; Adaptable; Self-assembled; Monolayers; Supramolecular chemistry; Cell adhesion; Biocensor;

    Abstract : The most well-studied two-dimensional biomimetic cellular membrane modelsare self-assembled monolayers (SAMs) and supported lipid bilayers (SLBs).The former has the advantage of control over ligand density, homogeneity andorientation, allowing unambiguous interaction studies.

  5. 3. 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

  6. 4. 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.

  7. 5. Self Assembled Monolayers for Quartz Crystal Microbalance based Biosensing

    Author : Annica Myrskog; Bo Liedberg; Sofia Svedhem; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The work in this thesis has been focused on developing surfaces for use in biosensor systems, especially for quartz crystal microbalances. The surfaces were prepared by adsorption of organosulfur molecules onto gold substrates, so called self assembled monolayers (SAMs). READ MORE
