Title:
Selective ion-sensing with membrane-functionalized electrolyte-gated carbon nanotube field-effect transistors 
Abstract:
In this work the ion-selective response of an electrolyte-gated carbon-nanotube field-effect transistor (CNT-FET) towards K+, Ca2+ and Cl− in the biologically relevant concentration range from 10−1 M to 10−6 M is demonstrated. The ion-selective response is achieved by modifying the gate-electrode of an electrolyte-gated CNT-FET with ion-selective membranes, which are selective towards the respective target analyte ions. The selectivity, assured by the ion-selective poly(vinyl chloride) based mem...    »
