文摘

•: Fe₃O₄ NSs/rGO was synthesized with well-dispersed and dense coverage of Fe₃O₄ NSs.
•: Fe₃O₄ NSs/rGO showed higher activity compared with Fe₃O₄ MSs/rGO and Fe₃O₄ NPs/rGO.
•: Sensitive colorimetric detection of ACh was achieved based on Fe₃O₄ NSs/rGO.
•: The presented colorimetric platform has the merits of simple, rapid, and low-cost.
