Luminescent optical sensors are required to be highly stable, sensitive, and selective, three crucial features that can be achieved by fabricating them by means of the layer-by-layer nano-assembly technique. This method permits us to tailor the sensors\u2032 properties at the nanometer scale, avoiding luminophore aggregation and, hence, self-quenching, promoting the diffusion of the target analytes, and building a barrier against the undesired molecules. These characteristics give rise to the fabrication of custom-made sensors for each particular application.<\/jats:p>","DOI":"10.3390\/s17122826","type":"journal-article","created":{"date-parts":[[2017,12,6]],"date-time":"2017-12-06T11:29:36Z","timestamp":1512559776000},"page":"2826","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Luminescence-Based Optical Sensors Fabricated by Means of the Layer-by-Layer Nano-Assembly Technique"],"prefix":"10.3390","volume":"17","author":[{"given":"Nerea","family":"De Acha","sequence":"first","affiliation":[{"name":"Department of Electric and Electronic Engineering, Public University of Navarra, E-31006 Pamplona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5219-989X","authenticated-orcid":false,"given":"Cesar","family":"Elosua","sequence":"additional","affiliation":[{"name":"Department of Electric and Electronic Engineering, Public University of Navarra, E-31006 Pamplona, Spain"},{"name":"Institute of Smart Cities (ISC), Public University of Navarra, E-31006 Pamplona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ignacio","family":"Matias","sequence":"additional","affiliation":[{"name":"Department of Electric and Electronic Engineering, Public University of Navarra, E-31006 Pamplona, Spain"},{"name":"Institute of Smart Cities (ISC), Public University of Navarra, E-31006 Pamplona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3311-0834","authenticated-orcid":false,"given":"Francisco","family":"Arregui","sequence":"additional","affiliation":[{"name":"Department of Electric and Electronic Engineering, Public University of Navarra, E-31006 Pamplona, Spain"},{"name":"Institute of Smart Cities (ISC), Public University of Navarra, E-31006 Pamplona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2487","DOI":"10.1109\/LPT.2016.2601625","article-title":"Multipoint Remote Methane Measurement System Based on Spectrum Absorption and Reflective TDM","volume":"28","author":"Sun","year":"2016","journal-title":"IEEE Photonics Technol.
