Magnesium oxide (MgO) nanoparticles are among the most promising classes of nanomaterials
due to the fact that they have a rapid metabolism, are biocompatible, and are relatively lightweight.
For a considerable amount of time, these particular types of nanomaterials have been the most desired
substitute for hefty metallic substances in applications including photodynamic treatment and cancer
therapy. The primary objective of this research is to Look into the catalytic activity and toxicity of MgO
nanoparticles that have a variety of shapes. In order to conduct an analysis of the MgO that was created,
X-ray diffraction, electron microscopy, and UV-visible spectroscopy were used. Staphylococcus aureus
(S. aureus) and Escherichia coli (E. coli) models that are clinically relevant were used in order to evaluate
the factors that are dependant on toxicity respectively. On the basis of the observation of the UV-vis spectra,
the highest absorbance was obtained, along with a peak absorption that was very noticeable. In order
to determine the band gap that corresponds to MgO nanoparticles, Tauc's figure was used.
