The goal of this study was to synthesize nickel oxide nanoparticles(NiO-NPs)by the sol-gel method,which involved the use of salvia macrosiphon boiss plant extract,Ni(NO3)2·6 H2 O as a capping agent,and a nickel precursor,*** synthesized NiO-NPs were characterized by Fourier transform infrared spectroscopy(FTIR),ultraviolet-visible(UV-Vis)spectrophotometer,X-ray diffraction(XRD),field electron scanning electron microscopy(FESEM)/energy-dispersive X-ray spectroscopy(EDX),thermo-gravimetric analysis/differential thermal analysis(TGA/DTA)and vibrating sample magnetometer(VSM)***,according to the results of UV-Vis,the gap band of nanoparticles was calculated to be in the range of about 2.9-3.9 *** photocatalytic activity of nanoparticles on methylene blue(MB)degradation was investigated and according to the results,about 80%MB was apparently degraded in the presence of NiO-NPs under UV-A light(11 W)after 5 h in pH^*** have evaluated the cytotoxicity of NiO-NPs on the multiple tumor cells by materials method,and all the utilized concentrations were observed to cause non-toxic effects;therefore,it can be suggested that these samples have the potential of being employed in different fields of medicine.
