Ultrasensitive Field‐Effect Biosensors Enabled by the Unique Electronic Properties of Graphene
Ultrasensitive Field‐Effect Biosensors Enabled by the Unique Electronic Properties of Graphene
This review provides a critical overview of current developments on nanoelectronic biochemical sensors based on graphene. Composed of a single layer of conjugated carbon atoms, graphene has outstanding high carrier mobility and low intrinsic electrical noise, but a chemically inert surface. Surface functionalization is therefore crucial to unravel graphene sensitivity …
