Abstract

Au–polydopamine (PDA)–Fe3O4 nanocomposites were synthesized by a seed-assisting growth method. In the synthesis, PDA was a secondary substrate for the growth of Au nanoparticles. In this paper the prepared Au–PDA–Fe3O4 nanocomposites were applied in the fabrication of an electrochemical sensor for direct electron transfer (DET) of hemoglobin (Hb) and detecting interleukin-6 (IL-6).
