文摘
- •
Synthesis of ABEI-Pd@AuNPs realized immobilization of ABEI without post-modification.
- •
Grafting Fc on the surface of ABEI-Pd@AuNPs achieved effective signal amplification.
- •
Simultaneously immobilizing ABEI and Fc contributed to good catalytic efficiency.
- •
Pd@AuNPs could further enhance the ECL intensity due to their catalytic properties.
