Článekpeer-reviewedpublished Otevřený přístup New applications of carbon paste electrodes for determination of biologically active organic compoun(Univerzita Pardubice, 2014) Zima, Jiří; Barek, Jiří; Dejmková, Hana; Wang, JosephIn this paper, new electrochemical determinations of selected biologically active compounds are described employing various types of carbon paste electrodes (CPE) in batch voltammetric methods (differential pulse voltammetry (DPV), direct current voltammetry (DCV), and cyclic voltammetry (CV)) and in HPLC with electrochemical detection (HPLC-ED) utilizing amperometric CPE sensors. The results for determination of cymoxanil, famoxadone, 2,4-dihydroxybenzophenone, 2-hydroxy-4-methoxybenzophenone, chlortoluron, carboxin, triclosan, diafenthiuron, and propyl gallate are compared and discussed. Glassy carbon spherical microparticles were used as carbonaceous component of the paste. The limits of detection of some analytes were below 1·10-7 mol l-1 in both batch and flow methods. The newly developed methods of determination were applied to model samples of drinking and river water, soils, and practical samples of edible oil, toothpaste, soap, and toilet water.Článekpeer-reviewedpublished Otevřený přístup Non-traditional electrode materials for detection of biomarkers(Univerzita Pardubice, 2014) Barek, Jiří; Moreira, Josino C.; Wang, JosephIn 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.
