Nanoparticles (MgO) utilising Justicia adhatoda and an evaluation of their antimicrobial properties

Abstract

Researchers are using safer green synthesis methods to make nanoparticles. Industry uses green synthetic methods more than physicochemical methods. Green MgO nanoparticle production is environmentally friendly, non-toxic, stable, and offers many nanoscale production options. Green synthesis methods can produce large amounts of nanoparticles, but there are still challenges. The biological extracts during synthesis prevent reaction mechanisms from being understood. Justicia adhatoda plant leaves were employed as a natural ligation agent to generate magnesium oxide nanoparticles. The functional group analysis was done with Fourier Transform Infra-Red spectroscopy. The green synthesized magnesium oxide NPs were crystalline and spherical, as shown by X-ray diffraction and scanning electron microscopy. Analytical investigations determined that particles are 22.96 nm in size. The antimicrobial studies were carried for the Justicia adhatoda MgO nanoparticles against few gram-positive and gram-negative bacteria and fungi. The binding effect was greater at higher concentrations than the control Gentamicin.
