“…The nanoparticles synthesized in the present study are predominantly spherical and crystalline in shape. Other studies have also reported the same shapes especially spherical, for fabricated zinc oxide nanoparticles (Anvekar, Chari, & Kadam, 2017;Hoseinpour et al, 2017;Jamdagni, Khatri, & Rana, 2018). Furthermore, XRD spectrum showed that the zinc oxide nanoparticles have hexagonal structures and their average diameter is 35.88 nm.…”

Nanoparticles are commonly synthesized chemically and because of their risk for living organisms and environment, safer synthesis methods are highly considered. This work was carried out to evaluate the acute toxicity of zinc oxide nanoparticles synthesized from Satureja hortensis on rainbow trout (Oncorhynchus mykiss) by static bioassay test. The average weight and length of trout fish used in the study were 20±3 g and 15±2 cm respectively. Three groups of the experimented fish were exposed to different concentrations (1, 10 and 100 mg/L) of ZnO nanoparticles. All the exposed fish were daily observed and dead fishes were immediately removed and recorded. The obtained data were statistically analyzed using probit regression method. The LC50 value at 96 h was found to be 25.50 mg/L for trout fish which makes this nanoparticle as a low toxicity substance in terms of toxicity classification. According to the results lifetime reduced with increasing the concentration of ZnO. Based on the obtained LC50 for the synthesized ZnO from Satureja plant in this study and comparison with that of the chemically fabricated in others work, it was revealed that the green nanoparticles synthesis is much less hazardous and a good alternative technique.

“…There are two types of nanoparticles namely metal and metal oxide nanoparticle them are very important but metal oxide nanoparticle such as CuO, TiO 2 and ZnO have semi properties. Now-a-days ZnO nanoparticle has great attention among researchers owing to its different characteristics such as conductivity and cytotoxicity [3 synthesis of ZnO nanoparticles from leaves such as Moringa oleifera, Lemon grass, C and Catharanthus roseus has already been reported [4][5][6][7][8]. In our point of view, ZnO nanoparticles from Jasminum Fluminense using Zinc acetate and Sodium hydroxide as starting material first time.…”

The main objective of the present study the green synthesis of Zinc Oxide [ZnO] nanoparticles utilizing aqueous leaf extract of Fluminense.` Zinc acetate [Zn(O 2 CCH 3 sodium hydroxide [NaOH] were used as starting materials and Jasminum Fluminense leaf extract is used as precursor in the synthesis of ZnO nanoparticles. The resultant nanopowder was characterized by using Ultraviolet [UV] Spectroscopy, Fourier Transform Infrared Spectroscopy [FTIR] and Transmission Electron Microscopic [TEM] studies. Formation of ZnO nanoparticles has been confirmed by UV spectroscopy and the TEM analysis spectacles tha synthesized ZnO nanoparticles are of face centered cubic (fcc) structure and the size is found to be around 20 nm. FTIR spectral analysis indicated the leaf extract acts as the reducing and capping agents on the surface of ZnO nanoparticles. This sim green approach may provide a useful tool to hefty extent in the synthesis of ZnO nanoparticles. synthesized nanostructures illustrate novel applications in many fields such as cosmetics, optoelectronics, sensors, transducers and biomedica science because it is environmentally friendly and does not involve any harmful substances
