Enzyme field-effect transistor or Enzyme Field Effect Transistors) ENFET) Bayv electronic parts are among the electric potential of chemical sensors have high sensitivity and selectivity compared to the power of biological active substances (like enzymes) are. Bayvsnsvrhay potential for conversion to electrical signals of biological response selected ion electrodes are used. In simplest form, this sensor includes a membrane enzyme Ghyrmthrk around a pH meter probe reaction in which expedited the production of biological or hydrogen ions are absorbed. Reaction took place alongside the thin layer of glass can cause changes in pH and can be directly read by a pH meter. Using such electrodes for high impedance and thus the flow is equal to zero from any interference with the biological reactions should be avoided.

.Half-membrane moisture possible, b Bayvkatalyzvr, c absorbent glass close to the membrane active, d probe pH, e the electric voltage difference between the internal electrodes Ag / AgCl is created in the f, g diluted hydrochloric acid, h reference electrode.
Parts of this enzyme on the desired insulation layer ion-sensitive field-effect transistor ion-selective field effect transistor or ISFET proved to be short. Automatically compensate for fluctuations of pH and ambient temperature actually ISFET transistor pair is used for this purpose that one of them very similar to conventional FET is designed except it includes a thin membrane of jelly is a specific enzyme.
