    Non-traditional electrode materials for detection of biomarkers
    (Univerzita Pardubice, 2014) Barek, Jiří; Moreira, Josino C.; Wang, Joseph
    In this paper, new electrochemical methods suitable for detection of various types of biomarkers (biomarkers of exposition, tumor biomarkers, and biomarkers of medical treatment) are briefly reviewed. Attention is paid to the use of non-traditional electrode materials (various forms of amalgam electrodes, boron doped diamond film electrodes, carbon paste and carbon film electrodes, etc.) for voltammetric (batch analysis) and amperometric (flowing systems) detection of above mentioned biomarkers.

    Voltammetric and amperometric determination of biologically active organic compounds using various types of silver amalgam electrodes
    (Univerzita Pardubice, 2014) Barek, Jiří; Fischer, Jan; Moreira, Josino C.; Wang, Joseph
    In this paper, possibilities of various types of silver amalgam electrodes for determination of micromolar and submicromolar concentrations of various electrochemically reducible biologically active organic compounds are reviewed. Attention is paid to the use of polished and mercury meniscus modified silver solid amalgam electrodes, silver amalgam paste electrodes both with and without pasting liquids, single crystal silver amalgam electrodes, composite silver amalgam electrodes, and porous silver amalgam electrodes. Main focus is on voltammetric application of above mentioned electrodes. However, their application in flowing systems (high performance liquid chromatography and flow injection analysis with electrochemical detection) is briefly discussed as well. The compatibility of various types of silver amalgam electrodes with preliminary separation based on solid phase extraction is demonstrated on determination of nanomolar concentrations of environmentally important compounds in model samples of drinking and river waters.
