“…In the same way, previous reports have shown that the color changes from green to yellow-brown [29][30][31] or dark brown [32][33][34] after the green synthesis of Ag-NPs. The ability of F. sycomorus leaf extract to reduce Ag + ions to Ag-NPs in the current study is in line with other studies that reported Ag-, Au-, and Cu-NPs formation through F. sycomorus extracts [35][36][37].…”

Nanoparticles effectively control most plant pathogens, although research has focused more on their antimicrobial than their nematocidal properties. This study synthesized silver nanoparticles (Ag-NPs) through a green biosynthesis method using an aqueous extract of Ficus sycomorus leaves (FS-Ag-NPs). The nanoparticles were characterized using SEM, TEM, EDX, zeta sizer, and FTIR. The TEM results showed that the synthesized NPs were nanoscale and had an average particle size of 33 ± 1 nm. The elemental silver signal at 3 keV confirmed the formation of Ag-NPs from an aqueous leaf extract of F. sycomorus. The FTIR analysis revealed the existence of several functional groups in the prepared Ag-NPs. The strong-broad band detected at 3430 cm−1 indicated the stretching vibration of -OH (hydroxyl) and -NH2 (amine) groups. The nematocidal activity of biosynthesized FS-Ag-NPs has been evaluated in vitro against the root-knot nematode Meloidogyne incognita at 24, 48, and 72 h. The FS-Ag-NPs at a 200 µg/mL concentration applied for 48 h showed the highest effectiveness, with 57.62% nematode mortality. Moreover, the biosynthesized FS-Ag-NPs were also tested for their antibacterial activity against Pectobacterium carotovorum, P. atrosepticum, and Ralstonia solanacearum. With the application of nanoparticles, the reduction in bacterial growth gradually increased. The most potent activity at all concentrations was found in R. solanacearum, with values of 14.00 ± 2.16, 17.33 ± 2.05, 19.00 ± 1.41, 24.00 ± 1.41, and 26.00 ± 2.83 at concentrations of 5, 10, 15, 20, and 25 µg/mL, respectively, when compared with the positive control (Amoxicillin 25 µg) with a value of 16.33 ± 0.94. At the same time, the nanoparticles showed the lowest reduction values against P. atrosepticum when compared to the control. This study is the first report on the nematocidal activity of Ag-NPs using F. sycomorus aqueous extract, which could be a recommended treatment for managing plant-parasitic nematodes due to its simplicity, stability, cost-effectiveness, and environmentally safe nature.

“…A comparison of both morin and morin/AgNPs spectra reveals several spectral changes. The morin spectrum showed a strong broad peak at 3466 cm −1 corresponds to the stretching vibrations of the phenolic hydroxyl groups (Zayed, Shalby, et al, 2022). This band got narrower with a slight shift to 3470 cm −1 in the morin/AgNPs spectrum.…”

Phytochemical‐conjugated silver nanoparticles (AgNPs) are believed to act as a bridge between nanotechnology and therapy. There is a significant need for green and mass production of such materials due to their extensive applications, especially in the biomedical sector. In this study, morin‐stabilized silver nanoparticles (morin/AgNPs) were synthesized on a massive scale using a one‐pot solid‐state technique. The reaction is achieved by ball milling of morin and silver nitrate powders at ambient temperature without any solvent or toxic reagent. The prepared morin/AgNPs exhibited a semi‐hexagonal shape and ranged in size from 21 to 43 nm. The x‐ray diffraction results elucidated the formation of highly crystalline AgNPs. Fourier transform infrared and x‐ray photoelectron spectroscopic analyses prove that the hydroxyl, carbonyl, and aromatic functionalities in morin are playing major roles in the reduction and stabilization of AgNPs. The antioxidant potential of morin/AgNPs was evaluated utilizing 2,2‐Diphenyl‐1‐picryl‐hydrazyl (DPPH) assay. Morin/AgNPs exhibited better free radical scavenging activity (IC50 = 11.7 μg/mL) than morin (IC50 = 14.8 μg/mL). Furthermore, the synthesized AgNPs showed promising antimicrobial activity against Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus, Streptococcus mutans, and Candida albicans. The largest inhibition zones were observed against S. aureus (21.2 ± 0.6 mm) and K. pneumonia (20.3 ± 0.5 mm) bacteria. The foregoing results highlighted the prospective application of morin/AgNPs as a promising antioxidant and antimicrobial material for safe medical applications.Research Highlights A simple green route for the large‐scale production of AgNPs was developed. Morin acts as reducing/stabilizing agent in solid‐state synthesis of AgNPs. Morin/AgNPs exhibited promising antimicrobial and antioxidant activity.
