The sensor shows a linear pH slope of \u221259.1 mV\/pH, R2 = 0.9997, a hysteresis as low as 1.2 mV, and drift below 3.9 mV\/h. In addition, the redox interference performance of TiN electrodes is compared with that of Iridium Oxide (IrO2) counterparts. Experimental results show \u221232 mV potential shift (E0 value) in 1 mM ascorbic acid (reducing agent) for TiN electrodes, and this is significantly lower than the \u2212114 mV potential shift of IrO2 electrodes with sub-Nernstian sensitivity. These results are most encouraging and pave the way towards the development of miniaturized, cost-effective, and robust pH sensors for difficult matrices, such as wine and fresh orange juice.<\/jats:p>","DOI":"10.3390\/s21010042","type":"journal-article","created":{"date-parts":[[2020,12,23]],"date-time":"2020-12-23T12:19:51Z","timestamp":1608725991000},"page":"42","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Titanium Nitride Thin Film Based Low-Redox-Interference Potentiometric pH Sensing Electrodes"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7784-797X","authenticated-orcid":false,"given":"Shimrith","family":"Paul Shylendra","sequence":"first","affiliation":[{"name":"Electron Science Research Institute, School of Science, Edith Cowan University, Joondalup 6027, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5558-5403","authenticated-orcid":false,"given":"Wade","family":"Lonsdale","sequence":"additional","affiliation":[{"name":"School of Science, Edith Cowan University, Joondalup 6027, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3666-2175","authenticated-orcid":false,"given":"Magdalena","family":"Wajrak","sequence":"additional","affiliation":[{"name":"School of Science, Edith Cowan University, Joondalup 6027, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1969-3348","authenticated-orcid":false,"given":"Mohammad","family":"Nur-E-Alam","sequence":"additional","affiliation":[{"name":"Electron Science Research Institute, School of Science, Edith Cowan University, Joondalup 6027, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamal","family":"Alameh","sequence":"additional","affiliation":[{"name":"Electron Science Research Institute, School of Science, Edith Cowan University, Joondalup 6027, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"H29","DOI":"10.1149\/1.1353582","article-title":"A pH Electrode Based on Melt-Oxidized Iridium Oxide","volume":"148","author":"Yao","year":"2001","journal-title":"J.
