Abstract

Functionalized polysiloxanes can be used as sensing membranes in ion-sensitive field effect transistors (ISFETs). A new 0 ue-Si and reproducible route for obtaining well-de-fined polysiloxane copolymers–the anionic copolymerization of cyclotetrasiloxanes with different side groups (one of which is shown in the Figure)–is reported and the characterization and use of the copolymers in CHEM-FETS described.
