Characterization, antibacterial, anti-arthritic and in-vitro cytotoxic potentials of biosynthesized Magnesium Oxide nanomaterial

[Display omitted] •MgO nanomaterials were fabricated using Streptomyces sp.•MgO nanospheres were confirmed through FESEM and TEM.•MgO nanomaterials provide extraordinary toxicity against human breast cancer cell lines.•MgO nanomaterials were in 25 nm in size.•MgO nanomaterials have higher anti-bacterial agent and well suited for anti-arthritic activity. The spherical shaped Magnesium Oxide (MgO) nanomaterials were synthesized by the extracellular of Streptomyces sp. The Powder X-ray diffraction (PXRD) studies confirms that the particles were follows cubic crystal system and the absorbance peak around 275 nm is showed in UV–Visible spectrum confirms the MgO materials. The presence of the various functional groups in the synthesized material was studied by Fourier Transform Infrared spectroscope (FTIR) analysis. The abstemious stability of the synthesized material was studied by zeta potential analysis. Morphological studies such as Field Emission Scanning Electron Microscope (FE-SEM) and Transmission Electron Microscopy (TEM) show that the spherical nature of MgO has an average diameter of 25 nm. MgO Nanomaterials have been shown to provide remarkable effects against test cells and microorganisms in the Pharmaceutical field. Conclusive results from antibacterial, anti-arthritic, and anticancer studies were reported and have deduced that they provide remarkable effects.
