Abstract
(S/N = 3), significantly comparable to numerous existing immunosensors. Moreover, the minimum detection concentration of the designed immunosensor was about ten times smaller than that of many Bi and Mo-based sensors toward CEA detection, and the detection limit was lower, revealing higher sensitivity. The satisfactory selectivity and stability made the immunosensor potentially applicable for CEA detection in real samples.
