Impact of Preparation Technique on The Synthesis of Cr2O3 NPs and Investigation of Cytotoxicity Against the MCF-7 Breast Cancer Cell Line

Chemical precipitation method has been used to synthesis of Cr2O3 nanoparticles. The lattice parameters and crystallite size were investigated using X-ray diffraction (XRD) research. Transmission electron microscopy (TEM) and field emission scanning electron microscopy (FE-SEM) were used to examine the shape and chemical makeup of the Cr2O3  nanoparticles. The biological activity was discovered that the Cr2O3 nanoparticles had a major have a biological efficacy, through it was tested for their ability to inhibit the MCF-7 breast cancer cell line.
