| Abstract | A novel protocol of label-free electrochemical impedance immunosensor based on bovine serum albumin-nitidine chloride-reduced graphene oxide (BSA-NC-rGO) nanocomposite was proposed for quantitative determination of carcino-embryonic antigen (CEA). BSA was anchored to rGO via the aromatic plane of NC by pi-stacking interaction to realize bio-functionalization of rGO, and then gold nanoparticles (AuNPs) were electrodeposited onto the surface of BSA-NC-rGO nanocomposite. The morphology, conductivity and interaction of different nanocomposites were characterized by scanning electron microscopy, cyclic voltammetry, electrochemical impedance spectroscopy (EIS) and UV-vis spectrum. CEA monoclonal antibody (anti-CEA) was conjugated to AuNPs via gold-thiol chemistry to construct electrochemical immunosensing platform, and the specific immunoreaction between CEA and anti-CEA was monitored by EIS. Under optimum conditions, CEA could be quantified in a wide range of 0.1-200 ng mL(-1) (R=0.9948) with low detection limit of 0.067 ng mL(-1). The proposed immunosensor exhibited great potential for detecting blood samples. (C) 2015 Elsevier B.V. All rights reserved. |
