To address this challenge, we synthesized TP\u2013iron nanoparticles (TP-Fe NPs) through coordination-driven self-assembly. Comprehensive characterization (SEM, TEM, FTIR, and XRD) confirmed the successful formation of stable TP-Fe NPs, primarily mediated by phenolic hydroxyl and carbonyl groups. Among TP-Fe NPs, the TP3-Fe1 NPs exhibited superior performance, achieving DPPH and ABTS radical scavenging rates of 65.71% and 89.64%, respectively, and inhibition rates of 91.44% against E. coli and 88.67% against S. aureus. Furthermore, TP3-Fe1 NPs demonstrated excellent biocompatibility, showing no significant cytotoxicity to L929 cells at 0.01\u20130.1 mg\/mL. These findings highlight the potential of TP3-Fe1 NPs as a safe and effective material with dual functionality for antioxidant and antibacterial applications.<\/jats:p>","DOI":"10.3390\/foods14244337","type":"journal-article","created":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T15:41:12Z","timestamp":1765899672000},"page":"4337","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["One-Step Synthesis of Tea Polyphenol\u2013Iron Nanoparticles for Enhanced Antioxidant and Antibacterial Properties"],"prefix":"10.3390","volume":"14","author":[{"given":"Zhiwen","family":"Hu","sequence":"first","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenzhen","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"},{"name":"State Key Laboratory of Advanced Papermaking & Paper-Based Materials, College of Light Industry and Engineering, South China University of Technology, Guangzhou 510640, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingxin","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuyi","family":"Zou","sequence":"additional","affiliation":[{"name":"College of Biological Science and Engineering, Fuzhou University, Fuzhou 350122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaxuan","family":"Hu","sequence":"additional","affiliation":[{"name":"Rural Revitalization College, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1507-6545","authenticated-orcid":false,"given":"Tengjun","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanlei","family":"Lin","sequence":"additional","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yueyue","family":"Cai","sequence":"additional","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qibiao","family":"Weng","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Eel Breeding and Processing, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Pang","sequence":"additional","affiliation":[{"name":"College of Food Science, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9273-2652","authenticated-orcid":false,"given":"Jiebo","family":"Chen","sequence":"additional","affiliation":[{"name":"National Engineering Research Center of Sugarcane, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Baysal, G., Ate\u015f, K., Akbulut, A., and \u00d6zpinar, H.
