    Polymeric tyrosinase nanobiosensor system for the determination of endocrine disrupting bisphenol A
    (University of the Western Cape, 2011) Matyholo, Virginia Busiswa; Iwuoha, Emmanuel; Dept. of Chemistry; Faculty of Science
    The main objective of this work was to develop simple and sensitive electrochemical sensors for the detection of bisphenol A. To investigate the electrochemical behavior of BPA on a bare glassy carbon electrode. To apply the developed biosensor for the determination BPA by differential pulse voltammetry, electrochemical impedance spectrometry, square wave voltammetry and steady-state amperometry. To characterize the synthesized PDMA-PSS by cyclic voltammetry (CV), UV-Vis spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM).
