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).
