	abstract = {The use of “green” reagents for silver nanoparticles (AgNPs) synthesis represents an attractive alternative to
conventional methods, due to the abundance of available biomass with reducing properties. Herein, a flavonoid
compound, hesperidin, was used to produce AgNPs, and the resulting dispersion was applied to textile fabrics and
tested for its antimicrobial properties. Different ratios of flavonoid to the silver precursor (v:v) were prepared. The
formation of the nanoparticles was indicated by the presence of the SPR specific band in the UV–Vis spectra. For the
synthesis optimization, the DLS technique was used to determine the size and polydispersity of the AgNPs, while zeta
potential measurements were performed to assess their physical stability. For the dispersion with the optimal ratio,
particles with the average size (Zav ) of 93.55±3.51 nm were obtained, with a polydispersity index (PdI) of 0.259. For this
ratio, the value of the zeta potential (ξ.) was –28.80±1.54 mV, indicating that the dispersion is physically stable. The
nanoparticles were further characterized using SEM-EDS techniques to confirm the particles' nature and evaluate their
morphology. The AgNPs were deposited on textile samples, by direct soaking into the dispersion. The distribution of the
AgNPs on the textile samples fibres was evaluated by SEM and the chromatic parameters L*a*b* were determined
compared to the untreated samples. Antimicrobial tests were conducted against Escherichia coli, Staphylococcus
aureus, and Bacillus subtilis strains, according to the ISO 20743:2013 standard, and percentages of bacterial reduction
up to 99.99\% were obtained.},
