With a simple optofluidic method, a broadband radiation is encoded in a time-domain interferogram and distributed to different sensing units that interrogate the sample simultaneously; the spectral readout of each unit is extracted from its output signal by a Fourier transform routine. The proposed method allows performing a multiparametric analysis of liquid samples in a compact setup where the radiation source, measurement units, and spectral readout are all integrated in a robust telecom optical fiber. An experimental validation is provided by combining a plasmonic nanostructured fiber probe and a transmission cuvette in the setup and demonstrating the simultaneous measurement of the absorption spectrum and the refractive index of water\u2013methanol solutions.<\/jats:p>","DOI":"10.3390\/s24030729","type":"journal-article","created":{"date-parts":[[2024,1,23]],"date-time":"2024-01-23T08:28:28Z","timestamp":1705998508000},"page":"729","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optrode-Assisted Multiparametric Near-Infrared Spectroscopy for the Analysis of Liquids"],"prefix":"10.3390","volume":"24","author":[{"given":"Maria Giulia","family":"Delli Santi","sequence":"first","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Istituto Nazionale di Ottica (CNR-INO), Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2894-111X","authenticated-orcid":false,"given":"Salvatore","family":"Castrignano","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Istituto Nazionale di Ottica (CNR-INO), Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marialuisa","family":"Capezzuto","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Istituto Nazionale di Ottica (CNR-INO), Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6208-3687","authenticated-orcid":false,"given":"Marco","family":"Consales","sequence":"additional","affiliation":[{"name":"Optoelectronics Group, Engineering Department, University of Sannio, C.so Garibaldi 107, 82100 Benevento, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7874-3352","authenticated-orcid":false,"given":"Patrizio","family":"Vaiano","sequence":"additional","affiliation":[{"name":"Optoelectronics Group, Engineering Department, University of Sannio, C.so Garibaldi 107, 82100 Benevento, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Cusano","sequence":"additional","affiliation":[{"name":"Optoelectronics Group, Engineering Department, University of Sannio, C.so Garibaldi 107, 82100 Benevento, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0638-428X","authenticated-orcid":false,"given":"Gianluca","family":"Gagliardi","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Istituto Nazionale di Ottica (CNR-INO), Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pietro","family":"Malara","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Istituto Nazionale di Ottica (CNR-INO), Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ozaki, Y., Huck, C., Tsuchikawa, S., and Engelsen, S.B.
