-Bacterial pollution is a great risk for human health. Nanotechnology offers a way to develop new inorganic antibacterial agents. Nano-inorganic metal oxide has a potential to reduce bacterial contamination. MgO is an important inorganic oxide and has been widely used in many fields. Many studies have shown that MgO nanoparticles have good antibacterial activity. Therefore, in this paper, the main synthesis methods, antibacterial activity and antibacterial mechanisms of MgO nanoparticles are reviewed.

Abstract. Green synthesis of nano MgO particles and their application in the formylationof isocyanates of N-Fmoc/Cbz/Boc protected amino acids were reported. Nano magnesium oxide catalysed reaction of isocyanate with 96% formic acid was established to obtain formamides. For this, the carboxyl group of protected amino acids was activated via mixed anhydride method and treated with NaN3. The formed azides were converted into their isocyanates through Curtius rearrangement and treated with HCOOH and catalytic amount of nano MgO. The advantages of this method were being remarkably simple and attaining economically low-cost nano metal oxide under milder reaction conditions. Most importantly, MgO could be easily separated and other basic impurities were removed through a simple work-up. This protocol showed high e ciency in catalysing the transformation in a greener fashion. The molecular docking study of the synthesized compounds was performed against the macromolecules sortase-A and glucosamine 6-phosphate synthase to understand the binding interactions. The results of in vitro antibacterial activities of the synthesized compounds were supported by docking analysis.

Solvent mixed spray pyrolysis technique has attracted a global interest in the synthesis of nanomaterials since reactions can be run in liquid state without further heating. Magnesium oxide (MgO) is a category of the practical semiconductor metal oxides, which is extensively used as catalyst and optical material. In the present study, MgO nanoparticles were successfully synthesized using a solvent mixed spray pyrolysis. The X-ray diffraction pattern confirmed the formation of MgO phase with an excellent crystalline structure. Debye-Scherrer equation is used for the determination of particle size, which was found to be 9.2 nm. Tunneling electron microscope analysis indicated that the as-synthesized particles are nanoparticles with an average particle size of 9 nm. Meanwhile, the ultraviolet-visible spectroscopy of the resulting product was evaluated to study its optical property via measurement of the band gap energy value.
