Physico-chemical characteristics and cytotoxicity evaluation of CuO and TiO nanoparticles biosynthesized using extracts of seeds.

The green synthesis approach to nanoparticles has been widely received as an alternative to the conventional methods, specifically for applications in areas such as biology, agriculture and medicine, where toxicity is of great concern. In this study, copper oxide (CuO) and titanium oxide (TiO) nanoparticles (NPs) were synthesized using an aqueous extract of seed. The morphology and structural characterization of the NPs were achieved by using scanning and transmission electron microscopy (SEM and TEM), and X-ray diffraction (XRD) measurement, while the elemental composition was studied using electron diffraction X-ray spectroscopy (EDS).
