Advantages

No lattice matching needed

Sliding ferroelectricity works in the lattice-mismatched MoS₂/ReS₂ heterojunction, broadening material choices.

Electrically regenerated interface

Polarization reversal enables a write-read-erase operation, electrically regenerating the sensing interface without chemical treatment.

Ultralow detection limit

The ferroelectric field-effect transistor biosensor achieves high sensitivity for label-free detection of 8-OHdG.

Applications

• Reconfigurable biosensors：Polarization reversal electrically regenerates the sensing interface, enabling repeated detection without chemical treatment.
• DNA damage biomarker detection：Enables high-sensitivity, label-free detection of the oxidative DNA damage biomarker 8-OHdG.
• Flexible electronics：The ultrathin 2D material-based transistor structure is compatible with flexible substrates.
