IH-Sal displayed a marked fluorescence increment with Zn2+. The detection limit (0.41 \u03bcM) of IH-Sal for Zn2+ was greatly below that suggested by the World Health Organization. IH-Sal can quantify Zn2+ in real water samples. More significantly, IH-Sal could determine and depict the presence of Zn2+ in zebrafish. The detecting mechanism of IH-Sal toward Zn2+ was illustrated by fluorescence and UV\u2013visible spectroscopy, DFT calculations, 1H NMR titration and ESI mass.<\/jats:p>","DOI":"10.3390\/s21165591","type":"journal-article","created":{"date-parts":[[2021,8,19]],"date-time":"2021-08-19T09:58:06Z","timestamp":1629367086000},"page":"5591","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["An Indole-Based Fluorescent Chemosensor for Detecting Zn2+ in Aqueous Media and Zebrafish"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2364-4653","authenticated-orcid":false,"given":"Donghwan","family":"Choe","sequence":"first","affiliation":[{"name":"Department of Fine Chem and Renewable Energy Convergence, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haeri","family":"So","sequence":"additional","affiliation":[{"name":"Department of Fine Chem and Renewable Energy Convergence, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soyoung","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Fine Chem and Renewable Energy Convergence, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hangyul","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Fine Chem and Renewable Energy Convergence, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ju Byeong","family":"Chae","sequence":"additional","affiliation":[{"name":"Department of Fine Chem and Renewable Energy Convergence, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiwon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Environmental Engineering, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1130-8698","authenticated-orcid":false,"given":"Ki-Tae","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Environmental Engineering, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheal","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Fine Chem and Renewable Energy Convergence, Seoul National University of Science and Technology (SNUT), Seoul 139-743, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7105","DOI":"10.1039\/C7CS00240H","article-title":"Fluorescent chemosensors: The past, present and future","volume":"46","author":"Wu","year":"2017","journal-title":"Chem.
