ChemFET, or Chemical Field Effect Transistor, is a type of a field effect transistor acting as a chemical sensor. It is a structural analog of a MOSFET transistor, where the charge on the gate electrode is applied by a chemical process. It may be used to detect atoms, molecules, and ions in liquids and gases.

ISFET, an ion-sensitive field effect transistor, is the best known subtype of ChemFET devices. It is used to detect ions in electrolytes.

ENFET is a CHEMFET specialized for detection of specific enzymes.
