摘要

•Au@Fe3O4@rGO nanocomposite sensor was fabricated to detect acetaminophen (AP).•The material was synthesised by simple co-precipitation method.•Au@Fe3O4@rGO shows high sensitivity and catalytic activity towards the oxidation AP.•The nanocomposite shows the detection limit of 5 nM for AP.•The sensor was successfully used to trace the quantity of AP in human urine sample.
