  2. 6. 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

  4. 7. 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

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

    Abstract : 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. READ MORE

  5. 8. lnterfacial Design and Characterization of Oligo(ethylene glycol) Self-Assembled Monolayers : Templates for Biomolecular Architectures

    Author : Ramūnas Valiokas; Stephen D. Evans; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents efforts to better understand and control the interfacial properties of oligo(ethylene glycol)-containing self-assembled monolayers (OEG SAMs) on gold. This has been done by means of molecular and interfacial design, followed by extensive characterization of the SAMs using a variety of surface analytical techniques. READ MORE

  6. 9. Molecular Adsorption on Self Assembled Monolayers studied by Surface Acoustic Waves and Infrared Spectroscopy

    Author : Lars Bertilsson; Antonio J. Ricco; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Chemical sensors based on the selective absorption of gas/vapors in polymer layers rely on molecular interactions. Details of the mechanisms involved can be obtained by studying the adsorption on well defined model organic surfaces. READ MORE

  7. 10. Affinity biosensors based on a capacitive transducer

    Author : Christine Berggren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembled monolayers; capacitance; heavy metal ion; non-labeled; nucleic acid; DNA biosensor; Biosensor; immunosensor; Analytical chemistry; Analytisk kemi;

    Abstract : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. READ MORE
