MgO@SiO2 nanocomposite was synthesized using mechanochemical method and
its formation was confirmed by FTIR and Uv-visible spectroscopic techniques.
The antibacterial effect of MgO@SiO2 nanocomposite was carried out on bacterial
isolates; gram-positive bacteria (Bacillus subtilis, Klebsiella pneunoniae) and gramnegative bacteria (Pseudomonas aeruginasa, Escherichia coli, and Salmonella typhi) using Agar well diffusion method. The results showed that MgO@SiO2 nanocomposite can find application as antibiotics against the investigated microbes.
