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).enPoly(2,5-dimethoxyaniline)Poly(4-styrenesulfonic acid)Bisphenol ATyrosinaseBiosensorGlassy carbon electrodeCyclic voltammetrySteady-state amperometryDifferential pulse voltammetrySquare wave voltammetryElectrochemical impedance spectrometryThesisUniversity of the Western Cape
