Silver nanoparticles can be prepared by using a microorganism. The objectives of the study were to determine the ability of Fusarium oxysporum BNT-02 in reducing silver nitrate solution to silver nanoparticles, to evaluate the effect of variations in treatment of textile materials toward antibacterial activity of textile materials impregnated with silver nanoparticles on Staphylococcus aureus ATCC 25924 and Escherichia coli ATCC 35218. In this study, silver nanoparticle were obtained by reducing the AgNO3 solution by F.oxysporum BNT-02. Coating of silver nanoparticles on textile materials was carried out by inserting sterile textile material into silver nanoparticle and shaking then drying. The textile material modified with silver nanoparticles was characterized for antibacterial activity against S.aureus ATCC 25924 and E.coli ATCC 35218. The inhibition zone to determine antibacterial activity was observed every 6 hours for 48 hours of incubation time. The inhibition zone data was analyzed using ANCOVA and t-test. The results showed that F.oxysporum BNT-02 can be used as a reducing agent for producing silver nanoparticles. The textile material coated with silver nanoparticles had antibacterial properties against S. aureus ATCC 25924 and E. coli ATCC 35218. Antibacterial activity of textile materials coated with silver nanoparticles on S.aureus ATCC 25924 showed a larger inhibition zone than E.coli ATCC 35218.

The purpose of this study was to synthesize silver nanoparticles (Ag NPs) using Sargassum sp. extract. Synthesized Ag NPs are used as antibacterial agents in woven fabrics. Sargassum sp. mixed with distilled water (1:4 w/v) then heated in the microwave for 1 minute with various power level at 60; 70 and 80. The extract obtained was dropped in an AgNO3 solution then heated in the microwave for 1; 3; 5; 7 and 9 minutes and obtained colloidal silver nanoparticle. Based on analysis using UV Vis obtained that Sargassum sp. extract can be used as a bioreductor in the preparation of silver nanoparticles. The Particle Size Analyzer (PSA) was used to obtain a particle diameter with z-average is 94.8 nm. Ag NPs applications on woven fabrics were characterized using XRD and NIR and antibacterial activity. XRD and NIR results show that Ag NPs has been deposited in woven fabrics, which is indicated by differences in spectra and diffractogram of the samples and blanks of woven fabrics. Woven fabrics deposited with Ag NPs provide antibacterial activity, both against S. aureus and E. coli bacteria.

Antibacterial and electrochemical evaluation of electrospun polyethersulfone/silver composites as highly persistent nanomaterials

et al. 2022

Silver‐based antibacterial nanoparticles have demonstrated indices of possible bacterial resistance after consecutive periods of time, limiting their application on antibacterial surfaces. In this work, we fabricate electrospun composites of polyethersulfone (PES) and silver nanoparticles (AgNPs), displaying highly‐persistent antibacterial behavior after 10 bacterial expositions. The herein‐reported membranes were synthesized by changing the Ag loading (0.05, 0.5, and 5 wt%), adding polyvinylpyrrolidone as a dispersion promoter, and the resulting composites were evaluated after a different number of bacterial expositions against Escherichia coli (E. coli) aiming to determine their bacterial tolerance. SEM micrographs revealed that the PES fiber diameters decreased as a function of the silver content from 798 to 398 nm, attributed to the conductivity and the viscosity improvement by AgNPs introduction in the polymer solution during the electrospun process. Moreover, the surface roughness (determined by atomic force microscopy) and the contact angle changed with the Ag content, increasing the hydrophilic behavior and promoting a better interaction with the bacteria suspended in the solution. Antibacterial activity kinetics of PES/AgNPs fibers showed 75% bacterial inhibition against E. coli in the composite with 0.5 wt% Ag after 3 h of exposition, and 75% after 1.5 h in composites with 5 wt% of Ag. The ca. 25% survival bacteria were used for consecutive bacterial tolerance assays, where the antibacterial behavior was constant after 10 expositions. Interestingly, electrochemical tests confirmed that PES fibers could control the silver‐releasing process. Thus, PES/AgNPs composites avoid the bacterial adaptation process, which makes them suitable as functional antimicrobial nanomaterials.
