▎ 摘　　要

This study reported the construction of a graphene sensor based on poly(3,4ethylenedioxythiophene)/Au nanoparticles, abbreviated as AuNPs/PEDOT/GR. The fabrication process consisted of two steps. First, the synthesis of PEDOT nanorods grown on graphene oxide nanosheets (PEDOT/GO) was conducted via liquid-liquid interfacial polymerization. Then, HAuCl4 was chemically reduced by NaBH4. The determination of anti-Mullerian hormone (AMH) was realized using a sensitive and facile AuNPs/PEDOT/GR-based immunosensor by measuring the electrochemical response variation before and after the immunoreaction.
