“…There are numerous reports on nanoparticles (NPs) synthesis, but rarely do they mention the scalability and/or reproducibility to make large-scale synthesis plausible, making these two factors the main roadblocks in bringing nanomedicine to the patient. Iron oxide, in particular its nanosized counterpart, is one such material that has been revolutionizing several different industries such as sensor components, [1][2][3] contrast/imaging agents, [4][5][6][7][8][9][10] targeted drug delivery, [11][12][13][14] magnetic nanoprobes, 15 nanocatalysts 16,17 and magnetically responsive materials. 18,19 In the field of medicine, iron oxide nanoparticles (IONPs) hold an advantageous place due to their non-toxic nature, biocompatibility, relative ease of functionalization, and, in some cases, their ability to act as magnetic hyperthermia mediators.…”

“…It has been reported that NPs have a strong toxic effect on plants, which depends on the dose and nature of nanoparticles [ 22 , 23 , 24 , 25 , 26 , 27 ]. Silver NPs have a positive role in the promotion of plant growth and enable the plant to defend against pathogens [ 28 , 29 ]. It was reported in spinach that exposure of TiO 2 NPs has significant effects on chlorophyll content, nitrogen metabolism and plant growth [ 30 ].…”

Nanoparticle (NP) application is most effective in decreasing metalloid toxicity. The current study aimed to evaluate the effect of Bacillus subtiles synthesized iron oxide nanoparticles (Fe3O4 NPs) against arsenic (As) stress on rice (Oryza sativa L.) seedlings. Different concentrations of As (5, 10 and 15 ppm) and Bacillus subtilis synthesized Fe3O4 NPs solution (5, 10 and 15 ppm) alone and in combination were applied to rice seedlings. The results showed that As at 15 ppm significantly decreased the growth of rice, which was increased by the low level of As. Results indicated that B. subtilis synthesized Fe3O4 NP-treated plants showed maximum chlorophyll land protein content as compared with arsenic treatment alone. The antioxidant enzymes such as SOD, POD, CAT, MDA and APX and stress modulators (Glycine betain and proline) also showed decreased content in plants as compared with As stress. Subsequently, Bacillus subtilis synthesized Fe3O4 NPs reduced the stress associated parameters due to limited passage of arsenic inside the plant. Furthermore, reduction in H2O2 and MDA content confirmed that the addition of Bacillus subtilis synthesized Fe3O4 NPs under As stress protected rice seedlings against arsenic toxicity, hence enhanced growth was notice and it had beneficial effects on the plant. Results highlighted that Fe3O4 NPs protect rice seedlings against arsenic stress by reducing As accumulation, act as a nano adsorbent and restricting arsenic uptake in rice plants. Hence, our study confirms the significance of Bacillus subtilis synthesized Fe3O4 NPs in alleviating As toxicity in rice plants.

“…In recent decades, the iron oxides nanoparticles have possessed exceptional features in sorption activities ascribing to their specific surface area, porosity structure, and high magnetic response, resulting in a remarkable sorption ability. In the same context, the iron oxides nanoparticles have existed in nature in diverse compositions, such as the hematite (α-Fe 2 O 3 ) and magnetite (Fe 3 O 4 ), whose suitable properties make them candidates in water remediation such as polymorphism that involves phase transition by temperatureinduction (Abdel Maksoud et al 2020a;Leonel et al 2021;Huang and Chen 2009;Nizamuddin et al 2019;Cornell and Schwertmann 2003;Hammad et al 2021).…”

Engineered magnetic oxides nanoparticles as efficient sorbents for wastewater remediation: a review

The rapid urbanization and industrialization is causing worldwide water pollution, calling for advanced cleaning methods. For instance, pollutant adsorption on magnetic oxides is efficient and very practical due to the easy separation from solutions by an magnetic field. Here we review the synthesis and performance of magnetic oxides such as iron oxides, spinel ferrites, and perovskite oxides for water remediation. We present structural, optical, and magnetic properties. Magnetic oxides are also promising photocatalysts for the degradation of organic pollutants. Antimicrobial activities and adsorption of heavy metals and radionucleides are also discussed.
