Early Detection of Carcinoembryonic Antigen Using Hollow Nanospheres Improves the Outcome of Pediatric Solid Tumors
A sandwich electrochemical immunosensor was developed for sensitive detection of carcinoembryonic antigen (CEA) using hollow nanospheres composite material loaded with gold nanoparticles as the signal tag and gold triangular nanoplate as the substrate material. Samples obtained from pediatric solid tumor tissue and their blood samples were used to detect CEA using this nanoparticle. The hollow nanospheres constructed in this study, provided abundant reaction sites and high catalytic activity, while the loading of Au NPs enhances conductivity and biocompatibility. The immunosensor has good analytical ability in detecting CEA in the mass concentration range of 1 pg/mL to 50 ng/mL, with a low detection limit (LOD) of 0.37 pg/mL. This novel method provides a valuable tool for rapid clinical detection of CEA in the context of pediatric solid tumors.
