Abstract
In a way to enhance performance of CHEMFETs based on chemically modifi ed polysiloxane membrane matrix, the effect of the polarity of polysil oxane material on the membrane homogeneity in relation to the covalent binding of the ionophore was investigated. Potassium sensors with the membrane based on the new polysiloxane showed a response with a Nerns tian slope in a whole investigated range of cation activity. A new pol ysiloxane as the membrane matrix improved its homogeneity and increase d the yield of functioning CHEMFETs.
