Issa and co-workers [15] proposed a chemically modified carbon paste electrode with Cu(II)-selective based on the etioporphyrin I dihydrobromide as potentiometric electrode to determinate Cu(II) in real samples.
In this paper, authors present a printed electronics-based approach to fabrication of the pH-sensitive potentiometric electrodes. Pastes prepared for screen printing of the functional layer of the transceivers were based on the previously developed conductive graphene composites [28] with addition of the ruthenium (IV) oxide as the proton-sensitive phase, of which response mechanism was described in detail elsewhere [29, 30].
