  2. 21. QCM-based sensing using biological and biomimetic interfaces

    Author : Louise Elmlund; Ian Nicholls; Teodor Aastrup; Jesper Wiklander; Kristina Nilsson-Ekdahl; Håkan Andersson; Susanne Wikman; Alessandra Maria Bossi; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quartz crystal microbalance; molecularly imprinted polymers; phage display; interactions; artificial receptors; recognition; selectivity; Kemi; Chemistry;

    Abstract : The objective of this thesis was to explore novel approaches for studying molecular recognition at biological and biomimetic surfaces using the quartz crystal microbalance (QCM) biosensor technique. The first two papers focused on the synthesis and study of biotin selective polymer films prepared using the molecularly imprinted polymer (MIP) technique. READ MORE

  4. 22. New Strategies for Preparing Polymers with Hierarchical Architectures

    Author : Natacha Ndizeye; Ian A. Nicholls; Alessandra Maria Bossi; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Liquid crystalline media; molecularly imprinted polymers; non-ionic deep eutectic solvents; quartz crystal microbalance; Organic Chemistry; Organisk kemi;

    Abstract : The objective of this thesis was to explore novel approaches for controlling morphologies and molecular recognition behaviour of polymers and to use these strategies in conjunction with the molecular imprinting technique in order to either enhance polymer performance in quartz crystal microbalance (QCM) sensor applications, or as an alternative to conventional solvents of polymerization. In Papers I and II, the use of liquid crystalline media in the synthesis of molecularly imprinted polymers was demonstrated. READ MORE

  5. 23. QCM-D with focus on variations in oscillation amplitude

    Author : Malin Edvardsson; Chalmers tekniska högskola; []
    Keywords : shear oscillation; actuator; Quartz crystal microbalance; amplitude; streptavidin; lipid vesicles; biosensor; colloidal particles; size distribution; QCM-D; protein binding; DNA hybridization; dual harmonic; lipid bilayer formation;

    Abstract : The QCM-D (quartz crystal microbalance with dissipation monitoring) technique is an increasingly popular tool in studies of molecular interactions at interfaces, e.g. binding/unbinding reactions at surfaces, studies of thin film properties, and conformational changes. READ MORE

  6. 24. Metals in Dynamic Chemistry: Selection & Catalysis

    Author : Brian J.J. Timmer; Olof Ramström; Stéphane Bellemin-Laponnaz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; constitutional dynamic chemistry; selection; multivalent interactions; carbohydrates; quartz crystal microbalance; catalyst screening; aqueous olefin metathesis; C-H activation; Kemi; Chemistry;

    Abstract : In the adaptation to the oxidative environment on earth, metals played a crucial role for the evolution of life. The presence of metals also allowed access to advanced functions due to their unique coordination sphere and reactivity. READ MORE

  7. 25. Characterization of Surfaces Designed for Biomedical Applications

    Author : Emma Kristensen; Hans Siegbahn; Rolf Larsson; Sven Oscarsson; Uppsala universitet; []
    Keywords : Physics; heparin; photoelectron spectroscopy; phosphorylcholine; biomaterial; quartz crystal dissipation; Fysik; fysik; Physics;

    Abstract : In order to develop blood biocompatible materials a heparin surface and a phosphorylcholine (PC) functionalized polymer surface were characterized using photoelectron spectroscopy (PES). The formation of the heparin surface was studied by quartz crystal microbalance with dissipation monitoring (QCM-D). READ MORE
