We developed an field effect transistor biosensor utilized graphene oxide nanoribbon for Methylene Blue (MB) sensing.

The GONR-FET demonstrated a 12.5 μA/mM sensitivity and 4.7 nM detection limit.

The materials quality of the GONR was improved and the domain size for the C=C sp2 bonding was improved after MB detection.
