Abstract

Cancer in human society is one of the most problematic health issue responsible for outnumbered deaths worldwide. The consumption of developed NPs in cancer diagnosis is a rapidly emerging field of bio-medical nanotechnology. Recent years, greener synthesized metal oxide hybrid nanoparticles have attracted great attention in cytotoxicity to different cancer therapy. Herein, we report that Duchesnea indica plant mediated green synthesis plant extract mediated Zn doped CuO (Zn/CuO) nanoparticles (NPs) prepared by hydrothermal method and these physico-chemical properties were characterized by XRD, UV-DRS, FTIR, and SEM with EDAX analytical techniques. The XRD pattern findings indicated that the crystal structure of the base CuO matrix are not distorted by the substitution of Cu²⁺ (0.73 Å) ions by Zn²⁺ (0.65 Å) ions. The average crystallite size of undoped and Zn/CuO NPs samples are found to be in between the range of 23 to 36 nm. And we can see that the Zn/CuO NPs are large aggregates, containing small particles with sizes of 100–300 nm with spherical shaped morphology by SEM and TEM microscopic images. The normal cell viability and cancer cell inhibition results on A-498 cancer cells and also normal human epithelial cells exhibited that no significant changes in the cell viability with normal kidney epithelial cells and doped NPs given excellent cell inhibition treated on A-498 kidney tumor cells.
