  2. 1. Synthesis of Substituted Alkanethiols Intended for Protein Immobilization : Chelate Associated Photochemistry (CAP)

    Author : Lan Bui; Peter Konradsson; Bo Liedberg; Markus Hederos; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The first and main part of this thesis is focused on the design and synthesis of photo-activableand metal chelating alkanethiols. Chelate associated photochemistry (CAP) is a novel conceptof combining two well-known protein (ligand) immobilization strategies to obtain a sensorsurface of covalently bound ligand with defined orientation.

    Abstract : 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. READ MORE

  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 inositolphosphoglycans found in Trypanosoma cruzi and development of novel carbohydrate monomolecular layers

    Author : Markus Hederos; Robert Madsen; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : In this thesis, synthetic carbohydrate chemistry has been utilized to contribute to the fundamental understanding of three biological relevant areas. These include parasite cell-membrane glycoconjugates, protein-resistant surfaces and antifreeze glycoproteins. READ MORE

  7. 5. Building Systems for Electronic Probing of Single Low Dimensional Nano-objects : Application to Molecular Electronics and Defect Induced Graphene

    Author : Syed Hassan Mujtaba Jafri; Klaus Leifer; Aidan Quinn; Uppsala universitet; []
