  • Hybrid biobateryy based on arylated carbon nanotubes and laccase

    Publication

    - BIOELECTROCHEMISTRY - Year 2012

    Single-walled carbon nanotubes (SWCNT) were covalently modified with antracene and antraquinone and used for the construction of cathodes for biocatalytic reduction od dioxygen. The nanotubes with aromatic groups casted onto the electrode increased the working surface of the electrode and enabled efficient direct electron tarnsfer (DET) between the enzyme and the electrode. the aryl groups enter the hydrophobic pocket of the T1...

  • Arylated carbon nanotubes for biobatteries and biofuel cells

    Publication

    - ELECTROCHIMICA ACTA - Year 2012

    Singlwalled carbon nanotubes (swcnts)covalently phenylated, napthylated or terphenylated were used for the construction of cathodes in a biobattery and in a biofuel cell. zn is the anode in the biobaterry and single-walled carbon nanotubes are covalently modified with glucose oxidase/catalase (swcnt-gox/cat) and the biofuel cell anode. the cell parameters were determined and the potentials of each of the electrodes under cell working...

  • Hybrid biobattery based on arylated carbon nanotubes and laccase

    Publication

    - BIOELECTROCHEMISTRY - Year 2011

    Jednościenne nanorurki węglowe modyfikowano resztami antracenu i antrachinonu Otrzymany materiał posłużył do modyfikacji elektrody węglowej w celu jej zastosowania do redukcji tlenu w bioogniwie paliwowym. Nanorurki z aromatycznymi grupami zwiększyły powierzchnię elektrody oraz przyczyniły się do zwiększenia bezpośredniego przeniesienia elektronów. Grupy arylowe mogą wnikać do hydrofobowej kieszeni enzymu, w której znajduje się...

  • Biobatteries and biofuel cells with biphenylated carbon nanotubes

    Publication

    - JOURNAL OF POWER SOURCES - Year 2014

    Single-walled carbon nanotubes covalently biphenylated are used for the construction of cathodes in a flow biobattery and in flow biofuel cell. Zinc covered with a hopeite layer is the anode in the biobattery and glassy carbon electrode covered with bioconjugates of single-walled carbon nanotubes with glucose oxidase and catalase is anode of the biofuel cell. The potentials of the electrodes are measured vs. the Ag/AgCl reference...

  • Oznaczanie tlenu – od metody Winklera do czujników enzymatycznych (Determination of oxygen – from Winkler Method to enzymatic sensor)

    Publication

    - Wiadomości Chemiczne - Year 2015

    Monitoring of dioxygen levels is of utmost importance from the view-point of life processes, medical diagnostics, nutrition and chemical industries. In all these measurements both low and high levels of this element are important. The common methods for the determination of dioxygen are the Winkler method, Clark electrode and pulsoxymeters. A new, already strong field of research can be now recognized – the development of miniaturized...

    - ELECTROCHIMICA ACTA - Year 2013

    Based on the known ability of perfluorodecalin/perfluorohydrocarbons to enhance oxygen solubility we modified oxygen sensitive biocathode by adding perfluorinated components to the catholite. This procedure improved the efficiency of the oxygen sensitive cathodes. Glassy carbon electrodes covered with single-wall carbon nanotubes (SWCNTs) with covalently bonded perfluoroaromatic groups were shown to be more sensitive to oxygen,...
