Abstract:An ion-selective field-effect transistor (ISFET) is chemically modified with a photopolymerizable and cyanopropyl modified polysiloxane containing N,N,N',N'-tetrabutyl-3,6-dioxaoctane-dithioamide as Cd2+ ionophore. This CHEMFET has a Nerstian response (30 mV/decade) to a change of cadmium activity in aqueous solutions. Selectivity coefficients of the CHEMFET towards potassium, calcium, copper, and lead are given. Preliminary results of the CHEMFET in a flow injection analysis cell without wire bonding and polymeric encapsulation are presented.
