US Patent 7692218 - CNT ChemFet

This patent is based on basic research from Rice University and appears to be basic to using carbon nanotubes as the channel for CHEMFET biosensors. Claim 1 reads:

1. A field effect transistor comprising:

a source;

a drain;

a gate;

a dielectric layer that coats the gate; and

at least one carbon nanotube disposed at least partially in said dielectric layer, said at least one carbon nanotube having a portion which is functionalized with at least one indicator molecule that is exposed from the dielectric layer, the at least one carbon nanotube being on the gate for transmitting charge from the at least one indicator molecule to the gate.
