Abstract

Dopamine (DA)detection is significant for the prevention of unfavorable neuronal illness. However, the detection of DA with low concentration still face tremendous challenges. In this study, highly ordered mesoporous Fe₃O₄ materials were synthesized as a biosensor by using mesoporous silica KIT-6 with different aging temperature as hard template. The ordered mesoporous Fe₃O₄ with high surface area modified glassy carbon electrode shows the high sensitivity for detecting DA. Fe₃O₄-40 mesoporous material modified electrode has the highest catalytic activity to DA with a sensitivity of 0.053 nA nM⁻¹ and a detection limit of 0.8 nM (S/N = 3). The results indicating that the mesoporous Fe₃O₄ material modified electrode exhibits high sensitivity to determine DA at low levels, which can be used for DA real-time monitoring in neutral biological media.
