Therefore, in recent years several efforts have been dedicated to the development of fast, sensitive, and selective sensors for the detection of heavy metal ions. In particular, fluorescent sensors have gained in popularity due to their interesting features, such as high specificity, sensitivity, and reversibility. Thus, this review is devoted to the recent advances in fluorescent sensors for the monitoring of these contaminants, and special focus is placed on those devices based on fluorescent aptasensors, quantum dots, and organic dyes.<\/jats:p>","DOI":"10.3390\/s19030599","type":"journal-article","created":{"date-parts":[[2019,2,1]],"date-time":"2019-02-01T03:08:05Z","timestamp":1548990485000},"page":"599","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":266,"title":["Fluorescent Sensors for the Detection of Heavy Metal Ions in Aqueous Media"],"prefix":"10.3390","volume":"19","author":[{"given":"Nerea","family":"De Acha","sequence":"first","affiliation":[{"name":"Department of Electric, Electronic and Communications Engineering, Public University of Navarra, E-31006 Pamplona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5219-989X","authenticated-orcid":false,"given":"C\u00e9sar","family":"Elos\u00faa","sequence":"additional","affiliation":[{"name":"Department of Electric, Electronic and Communications Engineering, Public University of Navarra, E-31006 Pamplona, Spain"},{"name":"Institute of Smart Cities (ISC), Public University of Navarra, E-31006 Pamplona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1298-5700","authenticated-orcid":false,"given":"Jes\u00fas","family":"Corres","sequence":"additional","affiliation":[{"name":"Department of Electric, Electronic and Communications Engineering, Public University of Navarra, E-31006 Pamplona, Spain"},{"name":"Institute of Smart Cities (ISC), Public University of Navarra, E-31006 Pamplona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3311-0834","authenticated-orcid":false,"given":"Francisco","family":"Arregui","sequence":"additional","affiliation":[{"name":"Department of Electric, Electronic and Communications Engineering, Public University of Navarra, E-31006 Pamplona, Spain"},{"name":"Institute of Smart Cities (ISC), Public University of Navarra, E-31006 Pamplona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,31]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2017).
