  1. 1. Spectroelectrochemistry of Redox Enzymes

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Andreas Christenson; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; complex II; bilirubin oxidase; laccase; enzyme mechanism; redox potential; electron transfer; spectroelectrochemistry; redox enzymes; Spectroelectrochemical cell;

    Abstract : A low volume and long optical path spectroelectrochemical cell was constructed and tested in a number of applications such as detection of direct electron transfer (DET) between redox enzymes and gold electrodes, determination of the formal potentials of redox centres in proteins and enzymes, as well as mechanistic studies of heterogeneous and intermolecular electron transfer of copper oxidases and succinate:quinine oxidoreductase (Complex II). The existence of DET between enzymes and electrodes was demonstrated for theophylline oxidase, cytochrome P450 cam, laccase, bilirubin oxidase, sulphite oxidase and Complex II. READ MORE

  2. 2. Characterisation of Organic Dyes for Solid State Dye-Sensitized Solar Cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
