Keywords: n Capparis zeylanican , Biosynthesis, MgO nanoparticles, Antimicrobial activities


The aim of the present study is green mediated synthesis of MgO nanoparticles using Capparis zeylanica L. leaf extracts for its biological applications. The optical, chemical and morphological properties of fabricated MgO nanoparticles were confirmed by XRD, UV–Vis spectroscopy, FT-IR, FE-SEM with EDAX respectively. The antimicrobial evaluation of synthesized MgO nanoparticles were investigated against microbial pathogens such as Staphylococcus epidermis, Enterococcus faecalis, Salmonella Paratyphi, Shigella dysenteriae, Candida albicans and Aspergillus niger using agar well method. UV visible absorption spectra and FT-IR analysis were used to investigate the optical characteristics and functional groups in MgO nanoparticles. Tetragonal crystalline structure was revealed by X-ray diffraction investigations. Synthesized MgO nanoparticles have a crystallite size of 32.6 nm. The green mediated synthesis of MgO nanoparticles was studied by FE-SEM with an average particle size of 42 nm. The green mediated synthesis of MgO nanoparticles was observed to have amazing antimicrobial activities. Therefore, in the present study, it is concluded that green mediated MgO nanoparticles are least expensive, pollution free and environmentally safest materials that are compatible for biological applications.
