UV\u2013Vis reflectance spectroscopy was used to measure the shift in the local surface plasmon resonance (LSPR) upon exposure to acetone, ethanol, 2-propanol, toluene, and water vapor. The optical responses were found to be substance-specific, as also demonstrated by principal component analysis. Point defects were introduced in the structure of the graphene overlayer by O2 plasma. The LSPR was affected by the plasma treatment, but it was completely recovered using subsequent annealing. It was found that the presence of defects increased the response for toluene and water while decreasing it for acetone.<\/jats:p>","DOI":"10.3390\/nano12142473","type":"journal-article","created":{"date-parts":[[2022,7,19]],"date-time":"2022-07-19T08:28:25Z","timestamp":1658219305000},"page":"2473","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Graphene-Encapsulated Silver Nanoparticles for Plasmonic Vapor Sensing"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7155-4025","authenticated-orcid":false,"given":"G\u00e1bor","family":"Piszter","sequence":"first","affiliation":[{"name":"Centre for Energy Research, Institute of Technical Physics and Materials Science, 1121 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4792-5516","authenticated-orcid":false,"given":"Gy\u00f6rgy","family":"Moln\u00e1r","sequence":"additional","affiliation":[{"name":"Centre for Energy Research, Institute of Technical Physics and Materials Science, 1121 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9790-3051","authenticated-orcid":false,"given":"Andr\u00e1s","family":"P\u00e1link\u00e1s","sequence":"additional","affiliation":[{"name":"Centre for Energy Research, Institute of Technical Physics and Materials Science, 1121 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0440-5446","authenticated-orcid":false,"given":"Zolt\u00e1n","family":"Osv\u00e1th","sequence":"additional","affiliation":[{"name":"Centre for Energy Research, Institute of Technical Physics and Materials Science, 1121 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"442","DOI":"10.1038\/nmat2162","article-title":"Biosensing with plasmonic nanosensors","volume":"7","author":"Anker","year":"2008","journal-title":"Nat.
