“…According to UV–vis spectroscopy of the mixture after 24 h of incubation, the maximum observed peak in this study was at 415 nm, which is closely related to spherically shaped NPs [ 39 ]. The optimum peaks for green-synthesized Ag-NPs are in the range of 400–460 nm, which is the corresponding absorption range of SPR for Ag-NPs ( Figure 2 A) [ 40 , 41 ]. The brownish or yellowish-brown color is formed as a result of excitation of surface plasmon resonance, which is particular for Ag-NPs as recommended previously [ 9 , 21 , 42 ].…”

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.

The bioreduction process, that utilizes the plant extracts, have been explored extensively as a green chemical route for the synthesis of metal nanoparticles due to their eco-friendly protocol as well as versatility in the selection of various plant resources. Recent advances in this plant extract mediated biological process are the fabrication of functional nanostructures. Bioreduction mechanism catalyzes the combining process of metal nanoparticles with other kind of materials including metal, metal oxides, cellulosic, zeolite and carbon nanomaterials. Integrating metal nanoparticles with various materials offers new functional properties and improves their performance comparing to their pristine counterpart. In this review, plant-based biochemical substances, which influence the metal ion into metal and their controlled nucleation on the surface of other kinds of materials are highlighted, and the future prospect of this bio-based synthesis of functional nanostructures are discussed.[a] M.

“…Among noble metal nanoparticles, Ag NPs have been the object of the attention of many researchers due to their particular characteristics, such as good conductivity, chemical stability, catalytic (Khodadadi, Bordbar, Yeganeh-Faal, & Nasrollahzadeh, 2017), and antimicrobial properties (Hajipour et al, 2012). Silver nanoparticles have been used in a lot of products including clothing (Mohanbaba & Gurunathan, 2016), textiles (Emam, El-Rafie, Ahmed, & Zahran, 2015), food packaging (Williams, Valencia, Gokulan, Trbojevich, & Khare, 2017), electronic components , as well as water disinfection systems (Tran, Nguyen, & Le, 2013), and the health industry (wound dressing, dental hygiene, catheters) (Yah & Simate, 2015).…”

The characteristics of the nanoparticles of silver, copper and zinc obtained from two synthetic routes were investigated. A possible future application of these nanoparticles is as bactericidal agents. The reduction methods were Aloe vera extract and gamma ray irradiation with a dose rate of 0.756 kGy/h and a total dose of 40 kGy from a 60Co-source. The chemical species of the nanoparticles (NPs) obtained by Aloe vera extract were Ag, CuO, and ZnO; while the NPs obtained using gamma irradiation were Ag and Cu2O. The precursor to obtaining the nanoparticles and the route of synthesis define the purity, morphology, crystallinity, and chemical speciation of the metal.
