1. A transistor biomolecule detector, comprising:
a nanocrystalline diamond layer,
at least one of a graphene oxide layer and a fluorinated graphene oxide layer on the nanocrystalline diamond layer, arranged to define separate hydrophilic and hydrophobic areas; and
a linker layer including a plurality of biomolecule receptors, wherein the transistor biomolecule detector functions as a biosensor field effect transistor.
