Nanostructured CeO2 was fabricated through a facile sonochemical route utilizing cerium (III) nitrate hexahydrate as a metal source and mentha extract as a novel capping agent. To our knowledge, this experimental work is the first successful endeavor for fabricating nanostructured CeO2 employing mentha extract by an easy and eco-friendly route. The microstructure and various characteristics of the oxide nanostructure prepared utilizing mentha extract were investigated using various methods. This research examined the anticancer effects of green synthesized cerium oxide nanoparticles (CeO2-NPs) on cancer cell lines (T98 and SHSY5Y) at several concentrations of 0.0, 0.05, 0.1, 0.2, 0.4, and 0.8 mg/ml NPs by exposure time of 24/48 h. The obtained results presented a cytotoxicity of the prepared NPs against the cancerous cell lines. Considering the CeO2-NP's effects on cancer cells indicated significant toxicity against cancer cell lines, these nanoparticles could be applied in medicine and in developing new drug formulations for cancer cell lines. Additional investigations are desired to reveal other biological applications of synthesized NPs against normal and other cancerous cell lines.
