  1. 1. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

    Författare :Christopher Schulz; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

    Sammanfattning : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. LÄS MER

  3. 2. Electrochemistry of Heme Containing Enzymes - Fundamentals and Applications

    Författare :Annika Lindgren; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phenol monitoring; spectroelectrochemistry; self-assembled monolayer; gold electrode; graphite electrode; direct electron transfer; cellobiose dehydrogenase; biosensor; peroxidase; kinetics; Electrochemistry; Elektrokemi;

    Sammanfattning : The thesis is a bioelectrochemical study of heme enzymes, mainly peroxidases and cellobiose dehydrogenases (CDH). It covers both fundamental and applied aspects, viz. studies of the direct electron transfer and kinetics of enzymes on electrodes, and the development of amperometric enzyme-based biosensors.

  4. 3. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Författare :Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. LÄS MER

  5. 4. Modelling electrooxidation of glycerol and methanol on close-packed transition metal surfaces

    Författare :Mikael Valter; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; implicit solvation; gold; Au 111 ; transition metals; biodiesel; electrochemistry; glycerol; DFT; van der Waals; methanol; scaling relations;

    Sammanfattning : Burning fossil fuels leads to excess CO2 in the atmosphere, causing global warming, threatening civilisation and ecosystems worldwide. As a step in making the society fossil-independent, we need to replace oil, coal, and gas in the transportation sector with fuels originating from sustainable energy sources. LÄS MER

  7. 5. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Författare :Alessia Mortari; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER
