Abstract
Two ways have been investigated for the preparation of urea ENFETs : covale nt bonding of urease directly on the surface of an ammonium sensitive FET a nd control of the diffusion of charged species into the enzymatic layer on pH-ISFET using additional charged polymeric membranes. Trichlorfon as a rep resentative pesticide is detected using a BuChE-FET sensor which is prepare d either with cross-linked BSA-glutaraldehyde membrane or photocross-linkab le PVA/SbQ (poly(vinyl alcohol) containing styryipyridinium) membrane.
