A novel protocol of electrochemical thrombin aptasensor based on a goldnanoparticles/thionine-graphene (AuNPs/Th-G) nanocomposite modified glassy carbon electrode was presented. Graphene was non-covalently functionalized by thionine viaπ-stacking interaction, and then AuNPs were electrodeposited onto the Th-G surface. The morphology and conductivity
