Manganese (Mn) is an important microelement for the mineral nutrition of plants, but it is not effectively absorbed from the soil and mineral salts added thereto and can also be toxic in high concentrations. Mn nanoparticles (NPs) are less toxic, more effective, and economical than Mn salts due to their nanosize. This article critically reviews the current publications on Mn NPs, focusing on their effects on plant health, growth, and stress tolerance, and explaining possible mechanisms of their effects. This review also provides basic information and examples of chemical, physical, and ecological (“green”) methods for the synthesis of Mn NPs. It has been shown that the protective effect of Mn NPs is associated with their antioxidant activity, activation of systemic acquired resistance (SAR), and pronounced antimicrobial activity against phytopathogens. In conclusion, Mn NPs are promising agents for agriculture, but their effects on gene expression and plant microbiome require further research.

“…Using the green protocol such as plant extracts, Microorganisms, and enzymes in nanoparticle synthesis is a new approach nowadays. The plant extract shows various benefits including the lack of any toxins and contaminants as well as being environmentally safe [ 25 , 26 , 27 ]. Recently it has been reported that herbal and medicinal plants were rich in many biologically active components such as flavonoids, amino acids, alkaloids, tannins, terpenoids, saponins, and phenolics which can be responsible for the reduction of metal to metal nanoparticles [ 27 , 28 , 29 , 30 ].…”

Theophrasite β-Ni(OH)2 nanocluster were fabricated via the sonochemical-assisted biogenic method using chia seeds extract as a reducing and stabilizing agent. The optical and morphological feature of the synthesized nanocluster was characterized using UV-Vis, FTIR, FE-SEM-EDS, HR-TEM, DLS, XPS, and XRD analysis. According to FE-SEM and HR-TEM images of the synthesized materials, β-Ni(OH)2 nanocluster illustrates the hexagonal particle shape with an average size of 5.8 nm, while the EDS results confirm the high purity of the synthesized nanocluster. Moreover, the XRD pattern of the synthesized materials shows typical peaks that match the reference pattern of the Theophrasite form of β-Ni(OH)2 with a hexagonal crystal system. The XPS analysis illustrates that the prepared samples exhibit both Ni2+ and Ni3+ with the predominance of Ni2+ species. Additionally the in-vitro cytotoxic activity of β-Ni(OH)2 nanocluster is tested against the MCF7 cell lines (breast cancer cells). The MTT assay results proved that the synthesized β-Ni(OH)2 nanocluster has potent cytotoxic activity against breast cancer cell lines (IC50: 62.7 μg/mL).

“…Therefore, it is necessary to find alternative methods for removing these pollutants before they can be released into the environment, and working on developing materials with high ability in 4-NP reduction is highly required [2]. There is a need to find effective and eco-friendly metal nanocatalysts for the environmental dropping of these organic contaminants [3][4][5]. At the nanoscale, CuO exhibits a unique structure and properties among mono-metal oxide.…”

Using safe and environmentally benign materials is considered one of the green chemistry approaches to avoid waste production. This research reported the biogenic synthesis of CuO nanoplates using Saussurea costus root extract assisted by a microwave sample preparation system. The phytochemical contents in the Saussurea costus root aqueous extract work as the reducing and capping agents for the nanoparticles. The biosynthesized CuO nanoplates were analyzed using UV–Vis spectroscopy, FT-IR, XRD, HR-TEM, DLS, FESEM, and EDS techniques. According to the HR-TEM and FE-SEM results, the CuO nanoparticles exhibited a plate-like shape with a mean size of 29 nm. Furthermore, the XRD results showed a typical agreement with the pattern of the monoclinic phase of copper oxide. The catalytic efficiency of the CuO nanoplates in the reduction of 4-nitrophenol to 4-aminophenol using NaBH4 was examined in terms of environmental catalytic activity. The reaction time took less than 10 min. Thus, CuO nanoplates synthesized via Saussurea costus root aqueous extract show high catalytic-activity potential for the environmental catalytic application of the removal of nitro pollutants.
