The recent expansion and availability of chemical modification methods has made it possible to generate a new class of electrochemically active ZnO nanorods. This reduction in size of ZnO (to a nanocrystalline form) using new growth techniques is essentially an example of the nanotechnology fabrication principle. The availability of these ZnO nanorods opens up an entire new and exciting research direction in the field of electrochemical sensing. This review covers the latest advances and mechanism of pH-sensing using ZnO nanorods, with an emphasis on the nano-interface mechanism. We discuss methods for calculating the effect of surface states on pH-sensing at a ZnO\/electrolyte interface. All of these current research topics aim to explain the mechanism of pH-sensing using a ZnO bulk- or nano-scale single crystal. An important goal of these investigations is the translation of these nanotechnology-modified nanorods into potential novel applications.<\/jats:p>","DOI":"10.3390\/s90907445","type":"journal-article","created":{"date-parts":[[2009,9,16]],"date-time":"2009-09-16T12:07:21Z","timestamp":1253102841000},"page":"7445-7480","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":85,"title":["The pH Response and Sensing Mechanism of n-Type ZnO\/Electrolyte Interfaces"],"prefix":"10.3390","volume":"9","author":[{"given":"Safaa","family":"Al-Hilli","sequence":"first","affiliation":[{"name":"Department of Science and Technology, Campus Norrk\u00f6ping, Link\u00f6ping University, SE-60174 Norrk\u00f6ping, Sweden"}]},{"given":"Magnus","family":"Willander","sequence":"additional","affiliation":[{"name":"Department of Science and Technology, Campus Norrk\u00f6ping, Link\u00f6ping University, SE-60174 Norrk\u00f6ping, Sweden"}]}],"member":"1968","published-online":{"date-parts":[[2009,9,16]]},"reference":[{"key":"ref_1","unstructured":"Kittel, C.
