An electrochemical immunosensor based on a combined amplification strategy with the GO–CS/CeO₂–CS nanocomposite for the detection of aflatoxin M₁

Abstract

Herein, a sensitive electrochemical immunosensor modified with graphene oxide–chitosan (GO–CS) and cerium oxide–chitosan (CeO₂–CS) using screen-printed electrodes (SPEs) was developed for the determination of aflatoxin M₁(AFM₁) in milk.
