For ion-sensitive devices with SiO2 sensing membrane, the pH sensitivity response has been analyzed when additional functional groups are attached on the SiO2 membrane. A modified Site-Binding model (SBM) and Gouy-Chapman-Stern (GCS) model are used for the theoretical analysis. In the presence of both silanol and amine groups, the highest pH sensitivity can… CONTINUE READING
