The properties of Graphene Oxide (GO) have been widely exploited in various sectors of science and technology, with promising results for gas sensing applications. This work combines both, the LMR-based sensing technology on planar waveguides and the use of a GO thin film as a sensitive coating, to monitor ethanol, water, and acetone. Experimental results on the fabrication and performance of the sensor are presented. The obtained results showed a sensitivity of 3.1, 2.0, and 0.6 pm\/ppm for ethanol, water, and acetone respectively, with a linearity factor R2 &gt; 0.95 in all cases.<\/jats:p>","DOI":"10.3390\/s23031459","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T02:01:18Z","timestamp":1675044078000},"page":"1459","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Gas Sensor Based on Lossy Mode Resonances by Means of Thin Graphene Oxide Films Fabricated onto Planar Coverslips"],"prefix":"10.3390","volume":"23","author":[{"given":"Ignacio","family":"Vitoria","sequence":"first","affiliation":[{"name":"Electrical, Electronic and Communications Engineering Department, Public University of Navarre, 31006 Pamplona, Spain"},{"name":"Institute of Smart Cities, Jeronimo de Ayanz Building, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4226-080X","authenticated-orcid":false,"given":"Elieser E.","family":"Gallego","sequence":"additional","affiliation":[{"name":"Electrical, Electronic and Communications Engineering Department, Public University of Navarre, 31006 Pamplona, Spain"},{"name":"Telecommunications and Electronic Department, University of Pinar del R\u00edo, Pinar del R\u00edo 20100, Cuba"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1083-3896","authenticated-orcid":false,"given":"Sonia","family":"Melendi-Espina","sequence":"additional","affiliation":[{"name":"School of Engineering, University of East Anglia (UEA), Norwich Research Park, Norwich NR4 7TJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7878-4704","authenticated-orcid":false,"given":"Miguel","family":"Hernaez","sequence":"additional","affiliation":[{"name":"School of Engineering, University of East Anglia (UEA), Norwich Research Park, Norwich NR4 7TJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6601-5449","authenticated-orcid":false,"given":"Carlos","family":"Ruiz Zamarre\u00f1o","sequence":"additional","affiliation":[{"name":"Electrical, Electronic and Communications Engineering Department, Public University of Navarre, 31006 Pamplona, Spain"},{"name":"Institute of Smart Cities, Jeronimo de Ayanz Building, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2229-6178","authenticated-orcid":false,"given":"Ignacio R.","family":"Mat\u00edas","sequence":"additional","affiliation":[{"name":"Electrical, Electronic and Communications Engineering Department, Public University of Navarre, 31006 Pamplona, Spain"},{"name":"Institute of Smart Cities, Jeronimo de Ayanz Building, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"751","DOI":"10.5094\/APR.2015.084","article-title":"A review of standards and guidelines set by international bodies for the parameters of indoor air quality","volume":"6","author":"En","year":"2015","journal-title":"Atmos.
