The present study reports a facile and simple method to prepare (Gold/Poly Anthranilic acid) (Au/PANA) core/shell nanostructures with uniform size and morphology in an aqueous solution through oxidation of the monomer (3-aminobenzoic acid) and reduction of the Au(III) ions simultaneously. In this work, gold nanoparticles were highly dispersed and stabilized by the oxidation of 3-aminobenzoic acid in order to form a uniform metal-polymer core/shell nanocomposite. Fabricated nanocomposites have been characterized by UV-Visible spectroscopy, attenuated total reflection-Fourier transform infrared (ATR-FTIR) and X-ray diffraction. Morphology of nanocomposites was analyzed by atomic force microscopy (AFM), scanning electron microscopy (SEM). Electroactivity of Au/PANA core/shells were investigated by electrochemical impedance spectroscopy (EIS) and equivalent circuit modeling was performed.
