In this work, edible fungus carbon quantum dots (Ef-CQDs) are synthesized via a facile hydrothermal route using edible fungus as a green carbon precursor, and a novel fluorescence sensing strategy is established for the rapid and selective detection of Cr3+ in environmental water matrices. Systematic optical investigations revealed that the as-prepared Ef-CQDs displayed outstanding selectivity toward Cr3+ over other coexisting metal ions. Meanwhile, the Ef-CQDs exhibited considerable scavenging activity toward hydroxyl radicals and DPPH radicals, endowing them with favorable antioxidant performance. When applied for Cr3+ determination in real environmental water samples, the proposed Ef-CQDs achieved satisfactory spiked recoveries ranging from 95.2% to 100.6%. This study provided a promising and sustainable approach for the green, rapid, and reliable monitoring of Cr3+ in complex aqueous environments.<\/jats:p>","DOI":"10.3390\/molecules31101585","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T12:05:22Z","timestamp":1778501122000},"page":"1585","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Sustainable Synthesis of Biomass-Based Carbon Quantum Dots for Selective Fluorescent Recognition of Cr3+ and In Vitro Antioxidant Applications"],"prefix":"10.3390","volume":"31","author":[{"given":"Yu","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, Guizhou University of Engineering Science, Bijie 551700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinying","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Guizhou University of Engineering Science, Bijie 551700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Liu","sequence":"additional","affiliation":[{"name":"Guizhou Key Laboratory for Germplasm Innovation and Resource-Efficient Utilization of Dao-di Herbs, Bijie Institute of Traditional Chinese Medicine, Bijie 551700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8550-9807","authenticated-orcid":false,"given":"Lifen","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Guizhou University of Engineering Science, Bijie 551700, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101653","DOI":"10.1016\/j.jksus.2021.101653","article-title":"Health and environmental effects of heavy metals","volume":"34","author":"Zaynab","year":"2022","journal-title":"J.
