Metal Oxide Nanoparticles (MONPs) have become an important section of nanoparticles, and these nanomaterials have been utilized in different application fields. Thus, it’s very important to understand the major and feasible synthesis methods that are involved during the production of MONPs. In our review, we are highlighting some major processes for their synthesis and morphology. This review highlights the status, potential, challenges, and feasibility of different processes like sol-gel, CVD, thermal, flame spray, biological synthesis, and other major techniques to synthesize and their applications. Synthesis of nanomaterial through environmentally friendly and greener routes, which greatly impacts different applications, has also been studied as it has received massive attention as a sustainable, feasible, reliable, and cost-effective route in different fields. These artificially created MONPs exhibit distinct physical and chemical characteristics owing to their substantial surface area and nanoscale dimensions. Their exceptional size, shape, and structure further influence their reactivity, resilience, and diverse properties. Thanks to these attributes, they find wide-ranging uses in commercial and domestic applications, such as catalysis, antimicrobial treatments, bio-sensors, electro-sensors, as well as agriculture and various other significant fields. This review paper states major applications of these MONPs have great aspects and potential in the future and will help researchers gain further insights into these fields.

Biosynthesized metal oxide nanoparticles are used as nano-fertilizers for sustainable agriculture as they have proven to be promising agents in increasing the germination rates and plant growth rate. Biosynthesis of copper oxide nanoparticles (CuO-NPs) was done for the first-time using extract of Mangifera indica leaves. Effects of as-synthesized CuO NPs on the seed germination of two legume seeds are investigated at different concentrations (0 - 2.5 mg/ml). UV-Vis and EDX analysis confirm the formation of CuO NPs & FESEM images revealed spherical shape of NPs with particle size ranging from 105nm to 155nm. CuO-NPs also revealed to be highly stable in aqueous suspension with zeta potential value -21.1mV. Germination rate, root /shoot growth and protein estimated of Cicer arietinum and Vigna radiata seeds found to be highest at 2.5mg/ml and 1mg/ml concentration, respectively. Negative impact on germination rate and root/shoot growth was observed due to toxic effects when CuO-NPs were applied at higher concentration 2.5mg/ml to Vigna radiata seeds. Thus, it is concluded that optimum concentration of biosynthesized CuO-NPs can be used to enhance the growth of leguminous seeds because of their possible interaction with the proteins and their up-regulation as confirmed by bioinformatics studies and molecular docking of protein.

Abstract
Herein, we have reported an easy process for the synthesis of superparamagnetic iron oxide nanoparticles (SPIOs, with a size of ~ 10 nm), where these SPIOs are surface-functionalized with novel pi-electron rich surfactants such as 1,4-benzene dicarboxylic acid (BDA) and 2-amino-1,4-benzene dicarboxylic ...

Herein, we have reported an easy process for the synthesis of superparamagnetic iron oxide nanoparticles (SPIOs, with a size of ~ 10 nm), where these SPIOs are surface-functionalized with novel pi-electron rich surfactants such as 1,4-benzene dicarboxylic acid (BDA) and 2-amino-1,4-benzene dicarboxylic acid (ABDA). The BDA/ABDA capped SPIOs have demonstrated well crystalline character, excellent colloidal stability, and high saturation magnetization. Moreover, these capped SPIOs have shown good heating ability in magnetic-hyperthermia studies under an alternating magnetic field at a medically suitable frequency, as compared to the previously reported SPIOs based heating-agents. Thus, the as-prepared BDA/ABDA-SPIOs can be used as promising heating agents for magnetic-hyperthermia based biomedical applications.
