Biosynthesis and characterization of ZnO nanoparticles using Lactobacillus plantarum VITES07

Green synthesis, characterization and antimicrobial activities of zinc oxide nanoparticles from the leaf extract of Azadirachta indica (L.)

“…From the image ( Fig.6 (a)) it is evident that the morphology of zinc oxide nanoparticles is spherical shaped and well distributed with aggregation observed which is very similar to earlier studies. However aggregation is also observed probably due to high surface energy of ZnO-NPs that usually occurs when synthesis is carried out in aqueous medium and also possibly due to densification resulting in narrow space between particles [26,19]. The EDS spectrum of ZnO-NPs show only the peaks of zinc and oxygen elements, which confirm ZnO-NPs, prepared is essentially free from impurities and it is seen in the limit of the EDS (Fig.6(b) ).…”

Biosynthesis, Characterization of Some Combined Nanoparticles, and Its Biocide Potency against a Broad Spectrum of Pathogens

“…As in Farhadi et al [27], the first band can be assigned to the O 2− → Co 2+ charge transfer process and the second one to the O 2− → Co 3+ charge transfer, which suggested formation of cobalt oxide. However, the UV-Vis optical absorption spectra of Ni and Zn reaction mixture appeared at 370 and 380 nm, respectively, indicating an almost uniform size of the NPs as highlighted by Sathyavathi et al [21] and Selvarajan and Mohanasrinivasan [28].…”

Cytotoxic effects of ZnO nanoparticles on mouse testicular cells

“…The profile shows seven peaks in the whole spectrum of 2θ values at 31.7°, 34.4°, 36.2°, 47.5°, 56.6°, 62.8°, and 68.0°. 32 These strong narrow diffraction peaks are indicative of the crystalline structure of the NPs. The sizes of ZnO NPs predicted from XRD data are consistent with Joint Committee on Powder Diffraction Standards file no 00-036-1451.…”
