The pH response of a pH-sensitive fieldeffect transistor (FET) is not affected by a ca. l-pm thick membrane formed from r-aminopropyltriethoxysilane and glutaraldehyde over the gate insulator by a vapor deposition method. The response between pH 5.5 and 8.5 is ca. 61 mV pH-' at 37Β°C in 5 mM Tris-HCl
New plasticizer-free polysiloxane membranes modified by trifluoropropyl groups were developed and investigated concerning the detection of different ions, e.g. K', Na+, Mg2+ and NO;. Ion-selective membranes prepared with a trifluoropropyl-functionalized polymer were deposited on ion-selective field-
The development of an ion-sensitive field-effect transistor for sodium ions is described, Calix[4]arene derivatives incorporated in a poly(viny1 chloride)-based membrane provide the selectivity. A poly(2-hydroxyethyl methacrylate) interlayer between the silicon dioxide gate and the sensing membrane
