Abstract:The design of durable chemical sensors based on field-effect transistors (FETs) is described. After modification of an ion-sensitive FET (ISFET) with a polysiloxane membrane matrix, it is possible to attach all electroactive components covalently. Preliminary results of measurements with a sodium-selective CHEMFET have shown that the durability is improved by the covalent attachment of the electroactive components ( > 90 days).
