CuFe2O4/reduced graphene oxide nanocomposite decorated with gold nanoparticles as a new electrochemical sensor material for ʟ-cysteine detection

A new electrochemical sensor based on glassy carbon electrode modified by CuFe2O4/reduced graphene oxide nanocomposite decorated with gold nanoparticles was developed for the electrochemical detection of ʟ-cysteine. In this study, CuFe2O4/rGO–Au nanocomposite was prepared and characterized by X-ray diffraction, Fourier Transform Infrared and Scanning Electron Microscopy. Electrochemical characterizations of the bare and modified glassy carbon...
