Abstract: Synthesis of MgO Nanoparticles by Green synthesis using Trigonella foenum-graecum is a facile method which can be easily used for various biomedical application. Construction of nanoparticle by this method makes it compatible for Antibacterial studies. Trigonella foenum-graecum functions as a reducing and stabilizing agent and the precursor is Magnesium Nitrate. The synthesised MgO nanoparticles was characterized using UV-Vis spectroscopy. FTIR technique which was used to confirm the presence of functional groups, X-ray Diffraction (XRD) study was used to confirm the crystalline nature of the biosynthesis nanoparticle and confirm the size of the nanoparticle as 13nm. GC-MS technique was used to confirm the presence of stabilizing and reducing functional groups present in the leaf extract. SEM with EDAX was used to confirm the size, shape and composition of green synthesized MgO nanoparticle. The effect of green synthesised MgO nanoparticle against gram positive and gram negative bacteria was also studied. And it was observed that MgO nanoparticle shows significant antibacterial activity towards both the stains.
