However, such sensors display poor performance in real sample matrices. A pH sensor employing a RuO2 pH-sensitive working electrode and a SiO2-PVB junction-modified RuO2 reference electrode is developed as an alternative high-performance solution. This sensor exhibits a performance similar to that of a commercial glass pH sensor in some common sample matrices, particularly, an excellent pH sensitivity of 55.7 mV\/pH, a hysteresis as low as 2.7 mV, and a drift below 2.2 mV\/h. The developed sensor structure opens the way towards the development of a simple, cost effective, and robust pH sensor for pH analysis in various sample matrices.<\/jats:p>","DOI":"10.3390\/s17092036","type":"journal-article","created":{"date-parts":[[2017,9,6]],"date-time":"2017-09-06T11:23:34Z","timestamp":1504697014000},"page":"2036","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["RuO2 pH Sensor with Super-Glue-Inspired Reference Electrode"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5558-5403","authenticated-orcid":false,"given":"Wade","family":"Lonsdale","sequence":"first","affiliation":[{"name":"Electron Science Research Institute, Edith Cowan University, Joondalup, WA 6027, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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, WA 6027, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamal","family":"Alameh","sequence":"additional","affiliation":[{"name":"Electron Science Research Institute, Edith Cowan University, Joondalup, WA 6027, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"095201","DOI":"10.1088\/0957-0233\/20\/9\/095201","article-title":"Water quality assessment by an integrated multi-sensor based on semiconductor RuO2 nanostructures","volume":"20","author":"Zhuiykov","year":"2009","journal-title":"Meas.
