Graphene oxide supported rhombic dodecahedral Cu2O nanocrystals for the detection of carcinoembryonic antigen
چکیده انگلیسی

In this work, a simple electrochemical immunosensor was developed for the detection of carcinoembryonic antigen (CEA) based on rhombic dodecahedral Cu2O nanocrystals–graphene oxide–gold nanoparticles (rCu2O–GO–AuNPs). GO as the template and surfactant resulting in rCu2O exhibit improved rhombic dodecahedral structure uniformity and excellent electrochemical performance. Moreover, GO was found to be able to effectively improve the long stability of rCu2O on the electrode response. Under optimal conditions, the immunosensor showed a low limit of detection (0.004 ng ml−1) and a large linear range (0.01–120 ng ml−1). This work presents a potential alternative for the diagnostic applications of GO-supported special morphology materials in biomedicine and biosensors.
