An electrochemical sensor for the sensitive and selective detection of cysteine is proposed based on a gold nanoparticle (AuNP)–iron(III) phthalocyanine (FePc) modified graphite paste electrode. The sensor was characterised using scanning electron microscopy (SEM/EDX), transmission electron microscopy (TEM), cyclic voltammetry and electrochemical impedance spectroscopy (EIS). Cyclic voltammetry studies demonstrated that the electrochemical behaviour of cysteine at the AuNP–FePc modified graphite...
