“…Regarding the production of ZnO, the oxide has been synthesized by a range of methods (Kołodziejczak-Radzimska and Jesionowski 2014), including the following: precipitation (Rodríguez-Páez et al 2001); Pechini-polymer complex (Avila et al 2004), combustion (Guo and Peng 2015), sol-gel (Alwan et al 2015); hydrothermal (Hardy et al 2009), mechanochemical (Anand et al 2014), hydro/solvo-thermal (Yan and Chuan-Shang 2009), and polyol process (Dakhlaoui et al 2009), among others.…”

In this work, a methodology of synthesis was designed to obtain ZnO nanoparticles (ZnO NPs) in a controlled and reproducible manner. The nanoparticles obtained were characterized using infrared spectroscopy, X-ray diffraction, and transmission electron microscopy (TEM). Also, we determined the antifungal capacity in vitro of zinc oxide nanoparticles synthesized, examining their action on Erythricium salmonicolor fungy causal of pink disease. To determine the effect of the quantity of zinc precursor used during ZnO NPs synthesis on the antifungal capacity, 0.1 and 0.15 M concentrations of zinc acetate were examined. To study the inactivation of the mycelial growth of the fungus, different concentrations of ZnO NPs of the two types of synthesized samples were used. The inhibitory effect on the growth of the fungus was determined by measuring the growth area as a function of time. The morphological change was observed with high-resolution optical microscopy (HROM), while TEM was used to observe changes in its ultrastructure. The results showed that a concentration of 9 mmol L -1 for the sample obtained from the 0.15 M and at 12 mmol L -1 for the 0.1 M system significantly inhibited growth of E. salmonicolor. In the HROM images a deformation was observed in the growth pattern: notable thinning of the fibers of the hyphae and a clumping tendency. The TEM images showed a liquefaction of the cytoplasmic content, making it less electron-dense, with the presence of a number of vacuoles and significant detachment of the cell wall.

“…Synthesis of ZnO Nps using eco-friendly routes received much attention by the researchers because they are clean, non-toxic, eco-friendly, free from unwanted byproducts, non-hazardous, require ambinet reaction temperature, etc. Recently, efforts were focused on the synthesis of size and shape controlled ZnO Nps by diverse methods [12,13]. However, the production of eco-friendly, low cost ZnO Nps in large scale by the existing routes still remain difficult [14].…”

“…The work of Eixenberger et al [25] showed that the presence of potential buffering systems in the biological material studied dramatically impacts the dynamics of ZnO-NPs, including their kinetics of dissolution, complex precipitate formation and toxicity profiles. ZnO has been synthesized by different methods [26][27][28][29][30][31][32][33][34][35][36][37][38]. To control the size and morphology of the ZnO particles synthesized, researchers have used surfactants [39], a strategy employed in the current work.…”

Controlled synthesis of ZnO nanoparticles and evaluation of their toxicity in Mus musculus mice

Zinc oxide nanoparticles (ZnO-NPs) of different sizes and morphology were synthesized. The variables analyzed were zinc precursor concentration, the nature of the synthesis solvent and the concentration of surfactant agent. The solids synthesized were characterized using IR spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). Considering the nature of the synthesis process, a tentative model of the mechanism of formation of the ZnO-NPs was proposed. ZnO-NPs with spheroidal morphology were obtained with a 10 mM CTAB concentration and these were selected to study their toxicity. For this study, Mus musculus mice were therefore given an oral dose of 50 mg ZnO/kg body weight (b.v.). Biopsies obtained from the livers and kidneys of the mice studied were analyzed using TEM and atomic absorption. The biopsy of the liver of the mouse given a dose of ZnO-NPs showed evidence of steatosis. The atomic absorption results showed the accumulation of Zn in both the liver and the kidney of the mouse.
