Herein, a flavonoid\u0000compound, hesperidin, was used to produce AgNPs, and the resulting dispersion was applied to textile fabrics and\u0000tested for its antimicrobial properties. Different ratios of flavonoid to the silver precursor (v:v) were prepared. The\u0000formation of the nanoparticles was indicated by the presence of the SPR specific band in the UV–Vis spectra. For the\u0000synthesis optimization, the DLS technique was used to determine the size and polydispersity of the AgNPs, while zeta\u0000potential measurements were performed to assess their physical stability. For the dispersion with the optimal ratio,\u0000particles with the average size (Zav ) of 93.55±3.51 nm were obtained, with a polydispersity index (PdI) of 0.259. For this\u0000ratio, the value of the zeta potential (ξ.) was –28.80±1.54 mV, indicating that the dispersion is physically stable. The\u0000nanoparticles were further characterized using SEM-EDS techniques to confirm the particles' nature and evaluate their\u0000morphology. The AgNPs were deposited on textile samples, by direct soaking into the dispersion. The distribution of the\u0000AgNPs on the textile samples fibres was evaluated by SEM and the chromatic parameters L*a*b* were determined\u0000compared to the untreated samples. Antimicrobial tests were conducted against Escherichia coli, Staphylococcus\u0000aureus, and Bacillus subtilis strains, according to the ISO 20743:2013 standard, and percentages of bacterial reduction\u0000up to 99.99% were obtained.","PeriodicalId":13638,"journal":{"name":"Industria Textila","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44715708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
