Ultrasensitive immunosensor for detecting CEA based on double amplified signal of graphene loaded CoFe2O4/Ag nanoparticles
Abstract Using Ag‐CoFe2O4‐GO nanocomposite as biosensor interface, a novel unlabelled electrochemical immunosensor was designed to detect tumour marker carcinoembryonic antigen. Here, Ag‐CoFe2O4‐GO was synthesized by one‐pot method as an immunological probe. They have the following advantages: (1) S...
