- •
A sensitive MMP-2 biosensor was constructed based on specific cleavage of peptide.
- •
Pt/Pd/mhCeO2NS was used as nanocarriers and electrocatalysts for the biosensor.
- •
The transduction of peptide cleavage events was combined with the electrocatalysts.
- •
The catalytic capacity of Pt/Pd/mhCeO2NS was optimal to the signal amplification.
- •
The electrochemical analytical performance was significantly improved and enhanced.
