Abstract

A polydopamine–Fe₃O₄ nanocomposite-based H₂O₂ electrochemical sensor is fabricated to real-time monitor the transmembrane release of reactive oxygen species from citral-treated Aspergillus flavus, revealing a mechanism involving transient transmembrane secretion of H₂O₂ for the citral-caused inhibition of aflatoxin production from a fungus for the first time.
