“…1, the six sample diffraction peaks prepared are consistent with the standard nano-ZnO standard card (89-0510). The diffraction peak is clear and sharp, which indicates that the nano-ZnO crystallization is better (Vijay et al 2020). By selecting all the diffraction peaks of the sample and calculating the integral area of the diffraction peak strength of the sample, the diffraction peak area (S t ) of different samples is obtained.…”

The microporous/mesoporous nano zinc oxide with a multi-level structure was successfully synthesized via using ethanol template. Ethanol not only improves the crystallinity of nano-ZnO, but also induce pore structure which provides more active sites for photocatalysis. The speci c B.E.T surface area of the nano-ZnO sample is 28.05m 2 /g, the pore volume is 0.069cm 3 /g, and the surface is covered with 1-30nm deep pits. The nanostructured structures at higher levels are composed of 300 to 500nm nanosheets.Compared with hard templates and other surfactant soft templates, this method of using Ethanol as a template not only has the advantages of green, simple reprocessing, and low price, but also provides an idea for synthesizing other multi-stage structures.

“…A rapid and large mass loss accompanied by a sharp endothermic peak occurred in the 370-405 °C range, producing a mass loss of roughly 50%. This thermal event is associated with the conversion of zinc hydroxide and/or zinc hydroxynitrate into ZnO, and the burn-off of organic matter in the residual fruit extract [32,33,34]. Thus, a calcination temperature of 375 °C was selected for all runs in the main experiment.…”

Zinc oxide nanoparticle was biosynthesized using Averrhoa bilimbi fruit extract as reducing and capping agent, with a focus on the impact of in-situ deagglomeration method on physical properties and pathogenic inhibition activity against Escherichia coli biofilm. Biosynthesis variables included deagglomeration method (ultrasonication vs. PVA as deagglomerant), temperature (30, 60 °C), and zinc precursor/plant extract volumetric ratio (1:2, 2:1). Upon calcination at 375 °C, crystalline ZnO nanoparticles with high phase purity were obtained. The final product formed soft agglomerates, as indicated by hydrodynamic mean particle diameters of 1.0-3.5 mm compared against mean individual particle diameter of 22 nm. Chemical deagglomeration and lower precursor/extract ratio promoted smaller agglomerates. Interaction between deagglomeration method and biosynthesis temperature implied that physical deagglomeration was more effective at higher temperature while the opposite applied for chemical deagglomeration. Antibiofilm activity of the nanoparticles was indicated by an average E. coli population reduction of 61% at 50 ppm ZnO dose, which increased to 78% at 200 ppm dose. Lower biosynthesis temperature and precursor/extract ratio increased antibiofilm activity, likely due to higher availability of residual plant extract biomolecules in the final ZnO nanoparticle product. Deagglomeration method did not directly impact the activity. However, the combination of chemical deagglomeration and higher ZnO dose produced a synergistic effect in inhibiting the E. coli biofilm growth. Overall, ZnO nanoparticle synthesized using Averrhoa bilimbi fruit extract exhibited promising antimicrobial activity against E. coli.

In the present study, we have improvised a biogenic method to fabricate zinc oxide nanoparticles (ZnO NPs) using chitosan and an aqueous extract of the leaves of Elsholtzia blanda. Characterization of the fabricated products was carried out with the help of ultraviolet−visible, Fourier transform infrared, X-ray diffraction, field emission scanning electron microscopy, highresolution transmission electron microscopy, selected area electron diffraction, and energy-dispersive X-ray analyses. The size of the improvised ZnO NP measured between 20 and 70 nm and had a spherical and hexagonal shape. The ZnO NPs proved to be highly effective in the antidiabetic test as the sample showed the highest percentage of enzyme inhibition at 74% ± 3.7, while in the antioxidant test, 78% was the maximum percentage of 2,2-diphenyl-1picrylhydrazyl hydrate scavenging activity. The cytotoxic effect was investigated against the human osteosarcoma (MG-63) cell line, and the IC 50 value was 62.61 μg/mL. Photocatalytic efficiency was studied by the degradation of Congo red where 91% of dye degradation was observed. From the various analyses, it can be concluded that the as-synthesized NPs may be suitable for various biomedical applications as well as for environmental remediation.
