A potentiometric disposable sensor strip for measuring pH in saliva

Zuliani, Claudio, Matzeu, Giusy and Diamond, Dermot orcid logoORCID: 0000-0003-2944-4839 (2014) A potentiometric disposable sensor strip for measuring pH in saliva. Electrochimica Acta, 132 . pp. 292-296. ISSN 0013-4686

In this paper, the preparation of a potentiometric strip for pH monitoring in saliva samples is reported. The potentiometric strip consists of a solid contact pH-selective and of a solidcontact ionogel reference electrode prepared on a dual screen printed substrate. The screen printing protocols, i.e., type of inks and number of deposits, were adjusted to relatively improve the batch reproducibility and the stability of the pH sensor. The pH of real saliva samples was monitored using the optimised potentiometric strip, and results were validated through parallel measurements with a standard laboratory method.
