A sensor in which an ion-selective electrode
is covered with a coating containing an enzyme which causes the reaction of an organic
or inorganic substance (substrate) to produce a species to which the electrode responds.
Alternatively, the sensor could be covered with a layer of substrate which reacts
with the enzyme, co-factor or inhibitor
to be assayed.
