文摘

•: A ECL sensor was assembled by rGO-BaYF5: Yb, Er prepared in situ hydrothermal.
•: ECL intensity of rGO-BaYF5: Yb, Er modified by AuNPs was enhanced 4-fold.
•: Immunosensor exhibited high selectivity to CEA with low detection limit.
•: The immunosensor was applied to a real sample (human serum samples).
•: The immunosensor has advantageous potential for future clinical analysis.
