“…In the FTIR spectrum in the range from 500 to 4000 cm −1 of such phytofabricated AgNPs, the following absorption peaks were observed: 3421, 2923, 1755, 1661, 1524, 1376, 1254, 1048, and 697 cm −1 . These absorption peaks were attributed to the O–H stretching vibrations (3421 cm −1 ) in alcohols, phenols, and flavonoids compounds [ 28 ], the C–H stretching vibrations (2923 cm −1 ) of aromatic compounds [ 27 ], the C=O stretching vibrations (1755 cm −1 ) for carbonyl compounds [ 29 ], the N–H stretching vibrations (1661 cm −1 ) of amide (I) in proteins [ 30 ], the C=C stretching vibrations (1524 cm −1 ) of aromatic compounds [ 31 ], the C–H stretching vibrations (1376 cm −1 ) in methylene moieties [ 32 ], the C–N stretching vibrations (1254 cm −1 ) of aliphatic amines [ 33 ], the C–O stretching vibrations (1048 cm −1 ) in alcohols and phenols [ 34 ], and finally, the C–H bonding vibrations (697 cm −1 ) of aromatic compounds [ 35 ]. In the FTIR spectrum of the O. persica leaf extract, the corresponding absorption peaks were observed at 3417, 2917, 2843, 1742, 1653, 1510, 1442, 1375, 1246, 1044, and 694 cm −1 , and as before related to the appropriate vibrations of the O–H, C–H, C–H, C=O, N–H, C=C, –OH, C–H, C–N, C–O, and C–H groups, respectively.…”

In the last years, the plant-mediated synthesis of nanoparticles has been extensively researched as an affordable and eco-friendly method. The current study confirms for the first time the capability of the Otostegia persica (Burm.) Boiss. leaf extract for the synthesis of silver nanoparticles (AgNPs). The phytofabricated AgNPs were characterized by ultraviolet–visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), and zeta potential analysis. Moreover, the total phenolic and flavonoids contents, and the antioxidant, antibacterial, antifungal, and anti-inflammatory properties of the phytofabricated AgNPs and the O. persica leaf extract were assessed. The results showed that the produced AgNPs were crystalline in nature and spherical in shape with an average size of 36.5 ± 2.0 nm, and indicated a localized surface plasmon resonance (LSPR) peak at around 420 nm. The zeta potential value of −25.2 mV pointed that the AgNPs were stable. The phytofabricated AgNPs had lower total phenolic and flavonoids contents than those for the O. persica leaf extract. The abovementioned AgNPs showed a higher antioxidant activity as compared with the O. persica leaf extract. They also exhibited significant antibacterial activity against both Gram-positive (Staphylococcus aureus, Bacillus subtilis, and Streptococcus pyogenes) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhi) bacteria. In addition, appropriate antifungal effects with the minimum inhibitory concentration (MIC) values of 18.75, 37.5, and 75 µg mL−1 against Candida krusei, Candida glabrata, and Candida albicans, respectively, were noted for this new bionanomaterial. Finally, the phytofabricated AgNPs showed dose-dependent anti-inflammatory activity in the human red blood cell (RBC) membrane stabilization test, being higher than that for the O. persica leaf extract. The resulting phytofabricated AgNPs could be used as a promising antioxidant, antibacterial, antifungal, and anti-inflammatory agent in the treatments of many medical complications.

“…Other studies have produced NPs from various plant extracts, where, also, differences in shape are expected to happen when using different structures from the same plant for the extraction process [ 79 , 80 ]. However, as reported by Rajakumar et al, the use of Eclipta prostrate leaves for AuNPs synthesis produced triangle, pentagon, and hexagon shapes [ 81 ].…”

Currently, metal nanoparticles have varied uses for different medical, pharmaceutical, and agricultural applications. Nanobiotechnology, combined with green chemistry, has great potential for the development of novel and necessary products that benefit human health, environment, and industries. Green chemistry has an important role due to its contribution to unconventional synthesis methods of gold and silver nanoparticles from plant extracts, which have exhibited antimicrobial potential, among other outstanding properties. Biodiversity-rich countries need to collect and convert knowledge from biological resources into processes, compounds, methods, and tools, which need to be achieved along with sustainable use and exploitation of biological diversity. Therefore, this paper describes the relevant reported green synthesis of gold and silver nanoparticles from plant extracts and their capacity as antimicrobial agents within the agricultural field for fighting against bacterial and fungal pathogens that can cause plant, waterborne, and foodborne diseases. Moreover, this work makes a brief review of nanoparticles’ contribution to water treatment and the development of “environmentally-friendly” nanofertilizers, nanopesticides, and nanoherbicides, as well as presenting the harmful effects of nanoparticles accumulation in plants and soils.

In this study, the antibacterial activity of cerium oxide nanoparticles on two Gram-negative and three Gram-positive foodborne pathogens was investigated. CeO2 nanoparticles (CeO2 NPs) were synthesized by a Wet Chemical Synthesis route, using the precipitation method and the Simultaneous Addition of reactants (WCS–SimAdd). The as-obtained precursor powders were investigated by thermal analysis (TG–DTA), to study their decomposition process and to understand the CeO2 NPs formation. The composition, structure, and morphology of the thermally treated sample were investigated by FTIR, Raman spectroscopy, X-ray diffraction, TEM, and DLS. The cubic structure and average particle size ranging between 5 and 15 nm were evidenced. Optical absorption measurements (UV–Vis) reveal that the band gap of CeO2 NPs is 2.61 eV, which is smaller than the band gap of bulk ceria. The antioxidant effect of CeO2 NPs was determined, and the antibacterial test was carried out both in liquid and on solid growth media against five pathogenic microorganisms, namely Escherichia coli, Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, and Bacillus cereus. Cerium oxide nanoparticles showed growth inhibition toward all five pathogens tested with notable results. This paper highlights the CeO2 NPs showed antibacterial activity with significant variations due to the differences in the membrane structure and cell wall composition among the two groups tested. Consequently, synthesized CeO2 NPs can be potential candidates for the treatment of osteomyelitis.
