文摘
- •
Pt nanoparticles and DNAzyme functionalized polymer nanospheres conjugations were synthesized.
- •
Electrochemical immunosensor was constructed based on the triple signal amplification strategy.
- •
The DPV current signals of electrochemical immunosensor were enhanced largely by the synergistic effect of polymer nanosphere, Pt NPs and DNAzyme.
