Determination of Quinine with Phosphotungstic Acid Modified Ion Sensitive Field Effect Transistor Sensor

We developed a new drug field effect transistor (drug-FET) sensor to detect the quinine concentration in medicinal solution. A drug sensitive membrane, prepared by adding electric active matter into a poly vinyl choride solution, and an ion sensitive field effect transistor were used to compose this sensor. The pH influence, selectivity and response curve… (More)
