“…The endophytic actinomycetes biomass filtrate and AgNO 3 solution did not show any color change after the same incubation period. The reduction efficacy could be attributed to the liberated electron from reducing NO 3 to NO 2 and then Ag + to Ag 0 ; therefore, the color intensity (in most cases) was related to the number of reduced Ag ions [ 34 ].…”

An endophytic strain of Streptomyces antimycoticus L-1 was isolated from healthy medicinal plant leaves of Mentha longifolia L. and used for the green synthesis of silver nanoparticles (Ag-NPs), through the use of secreted enzymes and proteins. UV–vis spectroscopy, Fourier-transform infrared (FT-IR), transmission electron microscopy (TEM), X-ray diffraction (XRD), and dynamic light scattering (DLS) analyses of the Ag-NPs were carried out. The XRD, TEM, and FT-IR analysis results demonstrated the successful biosynthesis of crystalline, spherical Ag-NPs with a particle size of 13–40 nm. Further, the stability of the Ag-NPs was assessed by detecting the surface Plasmon resonance (SPR) at 415 nm for one month or by measuring the NPs surface charge (−19.2 mV) by zeta potential analysis (ζ). The green-synthesized Ag-NPs exhibited broad-spectrum antibacterial activity at different concentrations (6.25–100 ppm) against the pathogens Staphylococcus aureus, Bacillus subtilis Pseudomonas aeruginosa, Escherichia coli, and Salmonella typhimurium with a clear inhibition zone ranging from (9.5 ± 0.4) nm to (21.7 ± 1.0) mm. Furthermore, the green-synthesized Ag-NPs displayed high efficacy against the Caco-2 cancerous cell line (the half maximal inhibitory concentration (IC50) = 5.7 ± 0.2 ppm). With respect to antibacterial and in-vitro cytotoxicity analyses, the Ag-NPs concentration of 100 ppm was selected as a safe dose for loading onto cotton fabrics. The scanning electron microscopy connected with energy-dispersive X-ray spectroscopy (SEM-EDX) for the nano-finished fabrics showed the distribution of Ag-NPs as 2% of the total fabric elements. Moreover, the nano-finished fabrics exhibited more activity against pathogenic Gram-positive and Gram-negative bacteria, even after 10 washing cycles, indicating the stability of the treated fabrics.

“…Extra NP solution on the TEM grid was eliminated by touching it to blotting paper. The grid was then kept at room temperature for drying [ 34 ]. The binding properties of silver nanoparticles were investigated by FT-IR analysis (Agilent system Cary 630 FTIR model, USA) in the range 400–4000 cm −1 .…”

“…Silver nitrate solution and/or biomass filtrate were tested as a negative control and did not exhibit any color change after the incubation periods. The reduction of Ag + to Ag 0 could be attributed to an electron released as a result of reducing NO 3 to NO 2 by metabolites involved in the biomass filtrate [ 29 , 30 ]; therefore, Ag-NPs color intensity was correlated with the number of reduced silver ions.…”

Improvement of the medical textile industry has received more attention recently, especially with widespread of microbial and viral infections. Medical textiles with new properties, such as bacterial pathogens self-cleaning, have been explored with nanotechnology. In this study, an endophytic actinomycetes strain of Streptomyces laurentii R-1 was isolated from the roots of the medicinal plant Achillea fragrantissima. This is used as a catalyst for the mediated biosynthesis of silver nanoparticles (Ag-NPs) for applications in the textile industry. The biosynthesized Ag-NPs were characterized using UV-vis spectroscopy, Fourier transform infrared (FT-IR), transmission electron microscopy (TEM), and X-ray Diffraction (XRD), which confirmed the successful formation of crystalline, spherical metal nanoparticles. The biosynthesized Ag-NPs exhibited broad-spectrum antibacterial activity. Our data elucidated that the biosynthesized Ag-NPs had a highly cytotoxic effect against the cancerous caco-2 cell line. The selected safe dose of Ag-NPs for loading on cotton fabrics was 100 ppm, regarding their antibacterial activity and safe cytotoxic efficacy. Interestingly, scanning electron microscope connected with energy dispersive X-ray spectroscopy (SEM-EDX) of loaded cotton fabrics demonstrated the smooth distribution of Ag-NPs on treated fabrics. The obtained results highlighted the broad-spectrum activity of nano-finished fabrics against pathogenic bacteria, even after 5 and 10 washing cycles. This study contributes a suitable guide for the performance of green synthesized NPs for utilization in different biotechnological sectors.

“…The common prominent peaks in all the spectra from plant extracts appeared in 3268-3290 cm −1 , 2347-2363 cm −1 , 2099-2103 cm −1 and 1635-1639 cm −1 . These highintensity peaks could be attributed to − OH vibration, -CN stretching, C≡C stretching, and C=O stretching, respectively [8,59,60]. Peaks at 2914/2919 cm −1 and 2851/2852 cm −1 appeared in both the seed extracts, which correspond to the C-H vibration in the − CH 2 group.…”
