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
