Graphene has been used among other things to design FETSEVICES that regulate the flow of electrons through a channel via a vertical electric field directed into the channel by a terminal called a gate.

In the realm of biosensing the physical gate is removed and the current in the channel is modulated by the binding between embedded receptor molecules and the charged target biomolecules to

whose surface potential (or conductivity) can be modulated by the interaction (known as conjugation) between the receptor and target molecules that results in net accumulation of charges over the gate region.
