The new materials were characterized by appropriate techniques (UV-Vis spectroscopy, SEM, and zeta potential analysis). Piezoelectric quartz crystal gold electrodes were coated with the different hybrids and their ability to interact with heavy metals was evaluated. The preliminary results obtained showed that the new materials can be explored for metal cations detection and the modification of the material surface is a key factor in tuning the metal selectivity.<\/jats:p>","DOI":"10.3390\/molecules23040867","type":"journal-article","created":{"date-parts":[[2018,4,10]],"date-time":"2018-04-10T13:06:08Z","timestamp":1523365568000},"page":"867","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["N-Confused Porphyrin Immobilized on Solid Supports: Synthesis and Metal Ions Sensing Efficacy"],"prefix":"10.3390","volume":"23","author":[{"given":"Sara","family":"Gamelas","sequence":"first","affiliation":[{"name":"Department of Chemistry and QOPNA, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Ana","family":"Gomes","sequence":"additional","affiliation":[{"name":"Department of Chemistry and QOPNA, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9373-7006","authenticated-orcid":false,"given":"Nuno","family":"Moura","sequence":"additional","affiliation":[{"name":"Department of Chemistry and QOPNA, University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"BIOSCOPE Group, LAQV@REQUIMTE, Chemistry Department, Faculty of Science and Technology, University NOVA of Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Maria","family":"Faustino","sequence":"additional","affiliation":[{"name":"Department of Chemistry and QOPNA, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5495-5126","authenticated-orcid":false,"given":"Jos\u00e9","family":"Cavaleiro","sequence":"additional","affiliation":[{"name":"Department of Chemistry and QOPNA, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5582-5446","authenticated-orcid":false,"given":"Carlos","family":"Lodeiro","sequence":"additional","affiliation":[{"name":"BIOSCOPE Group, LAQV@REQUIMTE, Chemistry Department, Faculty of Science and Technology, University NOVA of Lisbon, 2829-516 Caparica, Portugal"},{"name":"ProteoMass Scientific Society, Madan Park, Rua dos Inventores, 2825-182 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3718-4985","authenticated-orcid":false,"given":"Marta","family":"Ver\u00edssimo","sequence":"additional","affiliation":[{"name":"Department of Chemistry and CESAM, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1297-7057","authenticated-orcid":false,"given":"Tiago","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Department of Chemistry and CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6581-8880","authenticated-orcid":false,"given":"Ana","family":"Daniel-da-Silva","sequence":"additional","affiliation":[{"name":"Department of Chemistry and CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"M.","family":"Gomes","sequence":"additional","affiliation":[{"name":"Department of Chemistry and CESAM, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7953-8166","authenticated-orcid":false,"given":"Maria","family":"Neves","sequence":"additional","affiliation":[{"name":"Department of Chemistry and QOPNA, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"177","DOI":"10.1016\/j.jphotochem.2017.12.043","article-title":"Comparison of two procedures for the design of dye-sensitized nanoparticles targeting photocatalytic water purification under solar and visible light","volume":"356","author":"Youssef","year":"2018","journal-title":"J.
