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

   Författare :Sofia Svedhem; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : 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. LÄS MER

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

   Författare :Somsakul Watcharinyanon; Lars Johannson; Ellen Moons; Stacey Sorensen; Karlstads universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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.

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

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

   Sammanfattning : 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.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-assembled monolayer SAMs ; X-ray photoelectron spectroscopy XPS ; Near-edge X-ray absorption fine structure NEXAFS spectroscopy; Infrared reflection absorption spectroscopy IRRAS ; contact angle measurements; Kelvin probe measurements; oligo phenyleneethynylene OPE ; Porphyrin-functionalized OPE; Tetraphenylporphyrin; Ferrocene-terminated alkanethiol; thiol; silane; Au 111 ; Physics; Fysik; Physics; Fysik;

   Sammanfattning : Self-assembled monolayers (SAMs) provide well-defined and ordered films of molecules spontaneously chemisorbed on a surface. By designing molecules with desired functionalities, such molecular film can be interesting for a range of applications from molecular electronics to catalysis. LÄS MER
