| Abstract: | A novel strategy for simultaneous determination of three liver cancer biomarkers based on three redox labels with distinct voltammetric peaks was described. Gold nanoparticles coated carbon nanotubes were used as carriers to immobilize redox probes labeled antibodies and to amplify the signals. |
