  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. Structure of Self-Assembled Monolayers on Gold Studied by NEXAFS and Photoelectron Spectroscopy

    Författare :Somsakul Watcharinyanon; Lars Johansson; Hans Siegbahn; Karlstads universitet; []
    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

  4. 3. Molecular studies of initial atmospheric corrosion of copper : Exploration of ultra-sensitive techniques for the inhibiting effect of self assembled monolayers, and the effect of gamma radiation

    Författare :Saman Hosseinpour; Christofer Leygraf; Franz Geiger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; copper; self assembled monolayer; sum frequency spectroscopy; qcm; gamma radiation;

    Sammanfattning : Atmospheric corrosion indoors is of great practical importance for the degradation of metals, for example in electronics, military equipment, and cultural heritage items. It involves a wide range of chemical, electrochemical, and physical processes occurring in gas, liquid, and solid phases, and at the interfaces between them. LÄS MER

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

    Författare :Annica Myrskog; Bo Liedberg; Sofia Svedhem; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : 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). LÄS MER

  7. 5. Biosensor surface chemistry for oriented protein immobilization and biochip patterning

    Författare :Emma Ericsson; Karin Enander; Sofia Svedhem; Linköpings universitet; []
    Nyckelord :Biochip; biosensor; hydrogel; ligand; orientation; patterning; photochemistry; protein immobilization; surface chemistry; self-assembled monolayer; SAM;

    Sammanfattning : This licentiate thesis is focused on two methods for protein immobilization to biosensor surfaces for future applications in protein microarray formats. The common denominator is a surface chemistry based on a gold substrate with a self-assembled monolayer (SAM) of functionalized alkanethiolates. LÄS MER
