Iron‐based magnetic nanoparticles (MNPs) have been studied extensively for the past few decades. They have been applied in various applications, particularly in the biomedical sector. Due to their excellent physical and chemical properties, they have also been used widely in the agricultural sector. MNPs can be synthesized inexpensively and applied in large scale agricultural activities. This paper highlights the applications of iron‐based MNPs in the agricultural sector mainly as antimicrobial agents, plant growth promoters, site‐targeted delivery agents, nanosensors, detection and remediation for pesticide residue. Furthermore, the toxicity and transport of iron‐based MNPs in the soil‐plant system are also elucidated. These aspects have to be well‐understood before MNPs can be fully implemented effectively this pin the agricultural sector. Lastly, a hybrid nanomaterial, which is consisted of iron and magnesium oxide (MgO) nanoparticles (NPs), is proposed. This hybrid nanomaterial is expected to overcome the shortcomings of iron‐based MNPs.

The current work concentrated on the green synthesis of silver nanoparticles (AgNPs) through the use of aqueous Citruslimon zest extract, optimizing the different experimental factors required for the formation and stability of AgNPs. The preparation of nanoparticles was confirmed by the observation of the color change of the mixture of silver nitrate, after the addition of the plant extract, from yellow to a reddish-brown colloidal suspension and was established by detecting the surface plasmon resonance band at 535.5 nm, utilizing UV-Visible analysis. The optimum conditions were found to be 1 mM of silver nitrate concentration, a 1:9 ratio extract of the mixture, and a 4 h incubation period. Fourier transform infrared spectroscopy spectrum indicated that the phytochemicals compounds present in Citrus limon zest extract had a fundamental effect on the production of AgNPs as a bio-reducing agent. The morphology, size, and elemental composition of AgNPs were investigated by zeta potential (ZP), dynamic light scattering (DLS), SEM, EDX, X-ray diffraction (XRD), and transmission electron microscopy (TEM) analysis, which showed crystalline spherical silver nanoparticles. In addition, the antimicrobial and antioxidant properties of this bioactive silver nanoparticle were also investigated. The AgNPs showed excellent antibacterial activity against one Gram-negative pathogens bacteria, Escherichia coli, and one Gram-positive bacteria, Staphylococcus aureus, as well as antifungal activity against Candida albicans. The obtained results indicate that the antioxidant activity of this nanoparticle is significant. This bioactive silver nanoparticle can be used in biomedical and pharmacological fields.

The quest for new functional nanomaterials is one of the defining purposes of nanoscience and nanotechnology. A large number of metal nanoparticles (NPs) are extensively exploited for biomedical applications. Metal NPs, in particular platinum NPs (PtNPs), possess remarkable properties that make them a potential candidate as a diagnostic or therapeutic agent. Due to potential technological interest over the last decade, PtNPs have attracted much attention in the field of anticancer research. PtNPs, when conjugated with many functionalizing agents such as polymers, ligands, drugs, peptides, and surfactants, exhibit improved targeting and reduced cytotoxic effects in various cancers. The PtNPs conjugated with folic acid, graphene oxide, and iron NPs are gained more attention due to their stability, large surface area, and reduced toxicity. To achieve this goal, PtNPs are co‐loaded with drugs or other modalities that offer an opportunity for multimodal activity in the frame of treating cancer types focusing on breast, blood, lung, ovarian, skin, liver, etc. However, a review of PtNPs’ function in diagnosis and treatment is still lacking. In this review, the effectiveness of PtNPs toward inducing and elevating death of the cancerous cells proving its delivery approaches and antitumor nature, concluding with future perspectives, are summarized.
