A novel Au-nanoparticles/poly-eriochrome black T film modified glassy carbon electrode (AuNPs/PEBT/GCE) was constructed for the simultaneous determination of l-cysteine (L-Cys) and l-tyrosine (L-Tyr) by differential pulse voltammetry. Fourier transform infrared spectra and electrochemical impedance spectroscopy indicate that the PEBT film
