Detecting multiple tumor markers is of great importance. It helps in early cancer detection, accurate diagnosis, and monitoring treatment. In this work, gold nanoparticles–toluidine blue–graphene oxide (AuNPs-TB–GO) nanoparticles–carboxyl ferrocene–tungsten disulfide (AuNPs–FMC–WS2) nanocomposites were prepared for labeling Carcinoembryonic antigen (CEA) antibody Carbohydrate 72–4 (CA72-4) antibody, respectively, used as two kinds probes with different electrochemical signals. With the excellent magnetic performance biotin immune beads (IMBs), biofunctional IMBs firmly deposited on glassy carbon electrode (MGCE) surface by applying a constant field, then CEA CA72-4 immobilized avidin–biotin conjugation. The assay was based change detection peak current. Under optimum experimental conditions, linear range two-component immunosensor from 0.01 to 120 ng/mL, low limit 0.003 0.05 35 U/mL, 0.016 U/mL. results showed that proposed enabled simultaneous exhibited good reproducibility, high selectivity, sensitivity. particular, multiplexed immunoassay approach does not require sophisticated fabrication well-suited high-throughput biosensing application other areas.
