文摘
- •
A black phosphorous (BP) nanosheet field-effect transistor biosensor is reported.
- •
A surface passivation layer is used to enable stable operation of the BP biosensor.
- •
The biosensor shows fast response, high sensitivity, and selectivity for IgG protein.
- •
The sensing mechanism is dominated by the gating effect instead of charge transfer.
