Objective(s): Electrochemical estimation of dopamine by synthesized Pd@Au-PANI nanocomposite.Materials and Methods: Au-doped and Au-Pd incorporated PANI nanocomposites were prepared via oxidative polymerization and hydrothermal methods with ammonium persulphate. Results: As-suggested biosensor was improved for the simultaneous disclosure of dopamine and hydroquinone, displayed low detection limits of 0.46 µM for dopamine and 0.23 mM for hydroquinone. Conclusion: The fabricated biosensor showed broad linear ranges for dopamine (5-25 µM), and hydroquinone (0.5-2.5 mM). Along with these good results, the Au-Pd@PANI nanotube also implemented good stability and reproducibility.
