Facile Synthesis of Cobalt OxideNanoparticle for Biological Studies

Currently, Nanoparticles are utilized in various fields and have a different clinical application. In our research, we have developed the Cobalt oxide (Co3O4) NPs using the Sol-gel technique from the Cobalt chloride precursor. The synthesized nanoparticle was characterized by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Dynamic Light Scattering (DLS), and Fourier Transform Infra-Red Spectroscopy (FTIR). The cytotoxicity studies were evaluated on the Vero cell line (African green monkey kidney cell line) by using MTT assay at 72 hrs. The Cell viability which was observed during the process depends upon the concentration and time exposure. Moreover, the In-vitro cytotoxic effects of Co3O4 NPs showed a better result at the concentration of 50 μg/100μl in Vero cell
