“…According to these results, Ag NPs would be the main inhibitor of bacterial growth both in the presence and absence of Cu NPs. The antibacterial activity of Ag NPs is widely known, and the inhibition concentration can vary depending on the physicochemical properties of NPs. − However, the NP concentration range used in this study did not allow us to evaluate the minimum NP concentration that would determine the antibacterial activity difference between bimetallic NPs and Ag NPs.…”

This study aims to understand how properties of modified aluminosilicate geomaterials influence the antibacterial performance of nanocomposites when prepared with bimetallic nanoparticles (NPs).Copper/silver (Cu/Ag) bimetallic NPs were synthesized in the presence of imogolite (Imo), montmorillonite (Mtt), or zeolite (Zeo) using a simple onepot method and characterized for their crystal phases, micro-and nanomorphologies, particle size, elemental composition, and electrophoretic mobility. The antibacterial activity was evaluated through minimum inhibition concentration assays of NPs and nanocomposites for Gram (−) Escherichia coli and Gram (+) Staphylococcus aureus bacteria. Deposition of metallic Cu 0 , Ag 0 , and cuprite NPs was confirmed in Zeo_Cu/Ag and Imo_Cu/Ag nanocomposites, whereas only Cu 0 and Ag 0 were identified in Mtt_Cu/Ag. The bimetallic NPs were more uniformly distributed on Zeo and Mtt than Imo. Particle sizes of 28.1 ± 5.0, 9.4 ± 2.3, 10.1 ± 1.7, and 12 ± 1.3 nm were determined for Cu/Ag NPs, Imo_Cu/Ag, Mtt_Cu/Ag, and Zeo_Cu/Ag, respectively. The release rate of Cu and Ag ions from Zeo_Cu/Ag was higher than those of pristine Cu/Ag NPs and the other two nanocomposites. The antimicrobial action of bimetallic NPs and nanocomposites was dose-dependent in relation to the concentration of concerned materials and their stability in the medium. The physicochemical characteristics of Zeo resulted in a homogeneous distribution and low oxidation and agglomeration of Cu/Ag NPs, consequently increasing the antibacterial activity. Results of this study highlight the benefits of using a geomaterial support to achieve high antibacterial activity of bimetallic NPs, which could help reduce the consumption of pure Cu/Ag salts in NP-based antibacterial applications.

“…It can be concluded that the plant-mediated Fe 2 O 3 NPs were very essential on inhibiting the growth of AGE products . Similarly, Peron and colleagues synthesized silver nanoparticles from the pink Rosa damascena plant and have used them to minimize the effects of glucose levels and prevent the production of AGE products . A recent study reports that flavones exhibit stronger inhibitory effects on AGE products with respect to flavanones, flavonols, and isoflavones …”

The goal of the current study is to achieve plant-mediated synthesis of iron oxide nanoparticles (Fe 2 O 3 NPs). The plant extract of Saccharum arundinaceum was used as a reducing and stabilizing agent for the synthesis of Fe 2 O 3 NPs. Different techniques such as energy-dispersive X-ray analysis (EDX), X-ray diffraction (XRD), scanning electron microscopy (SEM), Fouriertransform infrared spectroscopy (FT-IR), and UV−visible spectroscopy (UV−vis) were used to characterize the synthesis of Fe 2 O 3 NPs. UV−visible spectroscopy verified the synthesis of Fe 2 O 3 NPs using a surface plasmon resonance peak at a wavelength of 370 nm. SEM analysis specifies the spherical morphology of the synthesized nanoparticles with a size range between 30 and 70 nm. The reducing and capping materials of Fe 2 O 3 NPs were revealed by FT-IR analysis based on functional group identification. The plant extract contained essential functional groups, such as C−H, C−O, N−H, −CH 2 , and −OH, that facilitate the green synthesis of Fe 2 O 3 NPs. The EDX analysis detected the atomic percentage with the elemental composition of Fe 2 O 3 NPs, while the XRD pattern demonstrated the crystallinity of Fe 2 O 3 NPs. Furthermore, the synthesized Fe 2 O 3 NPs showed potential antiglycation activity under in vitro conditions, which was confirmed by the efficient zone of inhibition on glycation of bovine serum albumin/glucose (BSAglucose) in the order <100 < 500 < 1000 μg/mL, which revealed that Fe 2 O 3 NPs showed significant antiglycation activity. Additionally, the cytotoxic activity against brain glioblastoma cells was assessed using the MTT assay, which exhibited diminished cytotoxic activity at concentrations lower than 300 μg/mL. Thus, we assumed that the resulting Fe 2 O 3 NPs are a good option for use in drug delivery and cancer treatments.

“…Moreover, both necrosis and vacuolar degeneration were dramatically increased in the AL group, which again was in line with other findings. However, RDA 1000 was significantly successful in lowering the damage in the mentioned aspects, which is likely due to its high protectivity characteristics by regulating the antioxidant system [ 61 , 62 ], reducing the ROS [ 63 , 64 ], and simultaneously increasing the antioxidant capacity of the body [ 64 , 65 ].…”

Aluminum (Al) is a popular metal in the industry, and its usage has greatly increased recently. The dose of this metal has been proven to be toxic to rats, but its effects on the offspring of the original receivers and prevention methods to reduce this damage are unknown. Rosa damascena is a well-known plant for its high antioxidant capabilities. In this study, the protective effect of Rosa damascena extract (RDA) on aluminum-induced lesions in the brain tissue of a rat offspring was investigated. In this regard, female rats were divided into seven groups, including the control group, the sham group, the aluminum group at the dose of 100 mg/kg, the extract groups at the doses of 500 and 1000 mg/kg, and the treatment groups that received the extract and Al at the same doses. After the treatment ended, the offsprings were subjected to exploratory behavioral tests, and finally, the tissues of the brain including the cerebral cortex, hippocampus, and hypothalamus were pathologically examined. It was observed that RDA at the dose of 1000 mg/kg reduced the malondialdehyde (MDA) and acetylcholinesterase (AChE) levels significantly ( P < 0.0001 ), while raising the catalase and FRAP indices in Al-treated rats. Moreover, it increased neuronal counts significantly and reduced necrosis and vacuolar degeneration in both the cortex and hippocampus compared to the Al-receiving group. In addition, the administration of RDA 1000 improved the behavioral test scores of the offspring. In conclusion, RDA can effectively reduce Al-induced damage in the brain tissue of the offspring.
