  1. 1. The Os polymer composites as a mediators enhancing and improving Glucose Biosensor/ biofuel cells and Neurotransmitter sensors : 2 nd generation of biosensors

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

    Författare :NAJAT BEDEN; Lunds universitet.; Lund University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enzyme immobilization; Neurocysticercosis: diagnosis; GDH biosensor; Os-polymers; PVP-Os-polymer; Composite Chitosan -Os-polymer; Dopamine sensor; multi anlytes sensors; GOx; CDH-based biosensor; Au-NPs-MWCNTS; PDH based sensor; Medited electron transfer; MET; DA; AA; and UA;

    Sammanfattning : Abstract: Different FAD dependent GDH enzymes together with the Os-redox polymer Os(4,4′-dimethyl-2,2′-bipyridine)2(PVI)10Cl]+ and a modified graphite electrode was shown to have distinct selectivity and high turnover rates towards glucose. The results of this study suggest that such electrodes may be applied either for glucose determination or as bioanodes in glucose biofuel cells. LÄS MER

  3. 3. Development of Second and Third Generation Bioelectronics

    Detta är en avhandling från Media-Tryck, Lund University, Sweden

    Författare :Federico Tasca; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow injection analysis; amperometric biosensor; mediated electron transfer; direct electron transfer; tryptophan repressor-binding protein; diaphorase; pyranose oxidase; cellobiose dehydrogenase; pyranose dehydrogenase; biofuel cell; spectroelectrochemistry; single wall carbon nanotubes; bioelectronics.;

    Sammanfattning : The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER
