Potentiometric response of lipid modified ISFET.
The gate surface of an ion-sensitive field effect transistor (ISFET) was modified with Langmuir-Blodgett (LB) film composed of fatty acid or crown ether amphiphiles to examine their potentiometric response to H+ and K+ ions. The results demonstrate the possible use of the lipid films for preparing ISFET ion sensors.
