Abstract :
The optimal conditions for the formation of a stable mixed urease/octadecylamine (ODA) film at the air–water interface are determined. This film is efficiently transferred onto the hydrophobized surface of a pH-ISFET, and the features of the urea enzymatic field-effect transistor (ENFET) are determined: detection limit 0.2 mM, response time 15 s, and dynamic range 0–20 mM.
