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.

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.

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.

Biogenic zinc oxide nanoparticles (BZnONPs) as a nano medicine attain high importance in the treatment of Peri Implantitis (PI). Present study was aimed to biosynthesize, optimize, characterize and evaluate the response of BZnONPs against PI triggering non periodontal pathogen. The BZnONPs synthesis, characterization, optimization and stability were based on UV-Visible, FTIR, XRD, FESEM, and EDX data. The BZnONPs were tested against S. aureus. Treatment of zinc acetate with Dimocarpus longan leaves extract resulted in formation of BZnONPs, which exhibited the absorbance signal between 350- 359 nm. Optimization study established 0.05 M zinc acetate, 6 ml of DLL aqueous extract, pH 12, and 2 h stirring time as parametric requirements for BZnONPs synthesis. Stability study of BZnONPs exhibited absorbance at 340 nm. The BZnONPs were characterized based on broad and shifted FT-IR bands, XRD signals (at 2θ values of 31.70◦ , 34.33◦ , 36.19◦ , 47.45◦ , 56.52◦ , 62.78◦ , 67.88◦ and 72.45◦ ), size range from 42.07-61.33 nm in FESEM, and elemental zinc 74.22 % in EDX spectrum. The BZnONPs exhibited high inhibitory response towards S. aureus. Present study establish that BZnONPs synthesis using Dimocarpus longan leaves aqueous extract is a facile method and reports that BZnONPs could be potential remedy for PI.
