Investigation on the structural, morphological, optical studies and antimicrobial performance of organic solvent assisted magnesium oxide (MgO) nanoparticles. Nanoparticles are in 16–18 nm of grain size prepared by sol–gel method. The XRD studies shows as synthesized products are in cubic phase with periclase structurer. The well disperesd spherical morphology were obtained in SEM and TEM. The organic solvent methanol had profound effects on the size of the nano particles. The optical absorption edge energy was present in UV region and the corresponding band gap energy values are 4.5 and 4.9 eV for water with ethanol and methanol mediated MgO sample respectively. The PL emission spectrum has a emission peak at 340 and 353 nm which is due to surface defects. The obtained MgO nanoparticles showed superior antimicrobial activities for the gram positive, gram negative and fungus strains using the ELISA reader at 450 nm.
