- •
We constructed an in-situ amplified sensing protocol for target Hg2+.
- •
T-Hg2+-T coordination chemistry was utilized during the measurement.
- •
DNase I-triggered target recycling was used for signal amplification.
- •
Target-induced oligonucleotide dissociation was employed from graphene oxide.
