The authors provide evidence that HS\u2212 binds the zinc center of all the complexes under investigation, allowing them to possibly function as sensors by a \u2018coordinative-based\u2019 approach. Naked-eye color changes occur when treating the systems with HS\u2212, so the fluorescence responses are modulated by the presence of HS\u2212, which has been related to a change in the energy level and coupling of excited states through a computational study. The results show the potential of the systems to function as HS\u2212\/H2S colorimetric and fluorescent sensors. Paper-strip-based sensing experiments foresee the potential of using this family of complexes as chemosensors of HS\u2212 in more complex biological fluids.<\/jats:p>","DOI":"10.3390\/s22093173","type":"journal-article","created":{"date-parts":[[2022,4,21]],"date-time":"2022-04-21T03:46:11Z","timestamp":1650512771000},"page":"3173","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Paper-Strip-Based Sensors for H2S Detection: A Proof-of-Principle Study"],"prefix":"10.3390","volume":"22","author":[{"given":"Maria","family":"Strianese","sequence":"first","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viktoriia","family":"Vykhovanets","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naym","family":"Blal","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Guarnieri","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3627-5535","authenticated-orcid":false,"given":"Alessandro","family":"Landi","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Lamberti","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Peluso","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4358-1776","authenticated-orcid":false,"given":"Claudio","family":"Pellecchia","sequence":"additional","affiliation":[{"name":"Dipartimento di Chimica e Biologia \u201cAdolfo Zambelli\u201d, Universit\u00e0 degli Studi di Salerno, Via Giovanni Paolo II, 132, 84084 Fisciano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1126\/science.1162667","article-title":"H2S as a physiologic vasorelaxant: Hypertension in mice with deletion of cystathionine gamma-lyase","volume":"322","author":"Yang","year":"2008","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"152","DOI":"10.1016\/j.jinorgbio.2017.04.021","article-title":"Spectroscopic investigation of the reaction of metallo-protoporphyrins with hydrogen sulfide","volume":"173","author":"Hartle","year":"2017","journal-title":"J.
