Therefore, it has great significance for sensitive and selective detection of DA. Herein, the AuPd@Fe<sub>2</sub>O<sub>3</sub> nanoparticles-based electrochemical (EC) sensor (AuPd@Fe<sub>2</sub>O<sub>3</sub> NPs/GCE) is developed for chronoamperometric detection of DA with high sensitivity and good anti-interference ability through simple immobilization of AuPd@Fe<sub>2</sub>O<sub>3</sub> nanoparticles on glassy carbon electrode (GCE) by Nafion. Under the application of oxidation potential, the AuPd@Fe<sub>2</sub>O<sub>3</sub> NPs/GCE exhibits good electrocatalytic activity toward DA, which enables to linearly detect DA in the range of 10 nM–831.61 μM (<em>R</em><sup>2</sup> = 0.9983). The AuPd@Fe<sub>2</sub>O<sub>3</sub> NPs/GCE also shows good selectivity and reproducibility for the detection of DA.

Secondly, we attempted to control the size of the alloy particles, which turned out to be the main challenge of this study.
