Electrochemical investigation of dopamine and hydroquinone by (Pd@Au-PANI) nanocomposite

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 ۰.۴۶ µM for dopamine and ۰.۲۳ mM for hydroquinone. Conclusion: The fabricated biosensor showed broad linear ranges for dopamine (۵-۲۵ µM), and hydroquinone (۰.۵-۲.۵ mM). Along with these good results, the Au-Pd@PANI nanotube also implemented good stability and reproducibility.
