Mixed urease/amphiphile LB films and their application for biosensor development
A Zhang, Y Hou, N Jaffrezic-Renault, J Wan… - …, 2002 - Elsevier
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.
