An important aspect for sensing devices is their long\u2013term stability. One of the more prominent changes that occur with porous silicon as it is exposed to atmosphere is oxidation. In this work we study the influence of oxidation on the sensing properties of porous silicon. Porous silicon layers were prepared by electrochemical etching and oxidized in a tube furnace. We observed that electrical resistance of oxidized samples rises in response to the increasing ambient concentration of organic vapours and ammonia gas. Furthermore, we note the sensitivity is dependent on the oxygen treatment of the porous layer. This indicates that porous silicon has a potential use in sensing of organic vapours and ammonia gas when covered with an oxide layer.<\/jats:p>","DOI":"10.3390\/s19010119","type":"journal-article","created":{"date-parts":[[2019,1,3]],"date-time":"2019-01-03T03:36:30Z","timestamp":1546486590000},"page":"119","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Sensing Properties of Oxidized Nanostructured Silicon Surface on Vaporized Molecules"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7935-7771","authenticated-orcid":false,"given":"Nikola","family":"Baran","sequence":"first","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hrvoje","family":"Gebavi","sequence":"additional","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9628-4647","authenticated-orcid":false,"given":"Lara","family":"Mikac","sequence":"additional","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davor","family":"Risti\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marijan","family":"Goti\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0049-1084","authenticated-orcid":false,"given":"Kamran Ali","family":"Syed","sequence":"additional","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mile","family":"Ivanda","sequence":"additional","affiliation":[{"name":"Laboratory for Molecular Physics and Synthesis of New Materials, Ru\u0111er Bo\u0161kovi\u0107 Institute, Bijeni\u010dka 54, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"011002","DOI":"10.1116\/1.5010249","article-title":"Engineering the interface between lipid membranes and nanoporous gold: A study by quartz crystal microbalance with dissipation monitoring","volume":"13","author":"Polat","year":"2018","journal-title":"Biointerphases"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"472","DOI":"10.1002\/elan.201600371","article-title":"A Simple and Highly Stable Porous Gold-based Electrochemical Sensor for Bisphenol A Detection","volume":"29","author":"Wannapob","year":"2017","journal-title":"Electroanalysis"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"405","DOI":"10.1016\/j.cclet.2017.06.021","article-title":"Ordered porous metal oxide semiconductors for gas sensing","volume":"29","author":"Zhou","year":"2018","journal-title":"Chin.
