- •
An Exo III-aided signal amplification strategy was proposed for protein detection.
- •
The MoSe2–Gr composite was prepared and employed to modify electrode.
- •
The aptasensor has been demonstrated with great selectivity and high sensitivity.
- •
This signal amplification strategy could be used for other biological targets.
