Antioxidant and Antibacterial Activities of Bio-synthesizedAl-Hanaa Nanoparticles

Abstract

This study examined the antibacterial and antioxidant properties of natural nanoparticles. Henna was employed as a free radical scavenger material at concentrations of 0.00030, 0.00035, 0.00040, 0.00045, and 0.00050 g/l, resulting from exposure to nuclear radiation in humans. Disk diffusion and the DPPH (2, 2-diphenyl-1-picrylhydrazyl) test were used to evaluate the bactericidal and antioxidant capabilities of the nanoparticles, respectively. According to the study's findings, gram-negative Escherichia coli (E. coli) bacteria was susceptible to the antibacterial action of the biosynthesized nanoparticles. The findings of the antioxidant test demonstrated that these nanoparticles have a concentration-dependent ability to eliminate DPPH radicals, resulting in a more powerful antioxidant activity at higher nanoparticle concentrations. Our findings concluded that Al-Hannaa nanoparticles have potential use in the food and pharmaceutical industries as a major source of antioxidants and antibacterial agents.
