AbstractIn this era, nanotechnology is gaining enormous popularity due to its ability to reduce metals, metalloids and metal oxides into their nanosize, which essentially alter their physical, chemical, and optical properties. Zinc oxide nanoparticle is one of the most important semiconductor metal oxides with diverse applications in the field of material science. However, several factors, such as pH of the reaction mixture, calcination temperature, reaction time, stirring speed, nature of capping agents, and concentration of metal precursors, greatly affect the properties of the zinc oxide nanoparticles and their applications. This review focuses on the influence of the synthesis parameters on the morphology, mineralogical phase, textural properties, microstructures, and size of the zinc oxide nanoparticles. In addition, the review also examined the application of zinc oxides as nanoadsorbent for the removal of heavy metals from wastewater.

The Impact

Nanoparticles are widely applied in all aspects of modern life because of their unique features such as small size and high surface area. Several types of research have been carried out to discover the feasible detrimental impacts of Nano-particles on human reproduction. The purpose of this study was to examine the impact of zinc oxide nanoparticles in mature male rats through examining LH, FSH, and testosterone sex hormones. Therefore, 30 Naked Mole-Rat Initiative (NMRI) rats were divided into 5 groups. Different doses of zinc oxide nanoparticles (250, 500 and 700 mg.kg-1) were intra peritoneally injected to animals only once. Then, the serum level of luteinizing hormone (LH), Follicle Stimulating Hormone (FSH), and testosterone hormones were measured using Enzyme-Linked Immunosorbent Assay (ELISA) method after 21 days. The results were analyzed by ANOVA and Tukey tests. The results indicated that zinc oxide nanoparticles doses caused a significant increase in FSH and testosterone level of blood (Respectively) in 250 and 700mg.kg-1 in comparison with the control group. Moreover, this research illustrated that zinc oxide nanoparticle can cause a dose-related increase in Testosterone and FSH hormones levels while causing no significant change in LH hormone level.

Zinc oxide (ZnO) nanoparticles recently are of significant consideration because of their applications as nontoxic metal oxides. This study is mainly intended to improve a simple, efficient, and environment-friendly method for preparation of ZnO nanoparticles. This process has been developed based on plant-intervened synthesis by making use of microwave Saturejahortensis aqueous extract. We have further characterized the obtained Zinc oxide nanoparticles by using different techniques. Additionally, their cytotoxic potential was inspected via MTT assay against both B lymphoma, A20 and T lymphoma, EL4 cells lines. The zinc oxide nanoparticle exposed cells for about 24 h showed diminished cell viability in the tested cell lines where EL4 cells has been reduced to 75% of control after 24 h, whereas A20 cells were lowered to 68% of control. ZnO-NPs have proficiently hindered EL4 cell DNA synthesis at 100 μg concentration whereas completely blocked the DNA proliferation at about 50 g concentration. However, A20 cells besides presented similar propensity, thus exploring the ZnO-NPs potential to treat lymphomas.

Plausible Mechanism

A novel approach has been described for the synthesis of zinc oxide nanoparticles by a very simple reaction of zinc metal with ethanol at 200°C. The diameters of the nanoparticles range from 50–200 nm. The reaction involves the cleavage of C–O bond of the alcohol, which occurs readily on the zinc metal surface. Addition of ethylenediamine to the reaction yields nanorods, thus acting as a shape-directing agent. A plausible mechanism is proposed for the formation of these nanostructures and it is expected that this synthetic technique can be extended to obtain other metal oxides.

Zinc oxide nanoparticles have wide applications as catalysts, antimicrobial agents, drug delivery agents, etc. because of their intrinsic properties. Various methods can be applied to synthesise nanoparticles, one of which is the biosynthesis process. Biosynthesis is more eco-friendly than chemical and physical methods. In the present study, the optimisation of zinc oxide nanoparticle biosynthesis using the yeast Saccharomyces cerevisiae was performed by applying a response surface method called the Box�Behnken design (BBD). Three factors were optimised in the present study, namely the concentration of zinc acetate as the precursor (X1), concentration of the S. cerevisiae fermentation broth (X2), and the incubation time (X3). The mass of zinc oxide nanoparticles (Y) was recorded as the response of the experiment. The product was then characterised by fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS), and particle size analyser (PSA). The optimum conditions for the preparation of zinc oxide nanoparticles were found to be 0.3 M, 100% (v/v), and 24 h as the zinc acetate concentration, medium concentration, and incubation time, respectively. The FTIR analysis showed peaks at ~600 cm−1, which is characteristic for ZnO stretching. From the XRD result, the ZnO nanoparticles with hexagonal structure was confirm. The SEM/EDS analysis confirmed that the morphology was spherical and showed the major energy emission for zinc and oxygen. Moreover, the PSA analysis revealed that the smallest size was 218.6 nm (12%) when the synthesis was performed at the optimum conditions, while when the incubation time was prolonged for 120 h, the size decreased to 134.2 nm.
