Green synthesis of AgO nanoparticles using Prosopis Cineraria bark extract and its antibacterial activity

Abstract The green synthesis of AgO nanoparticles (NP) uses plant elements like terpenoids, polyphenols, carbohydrates, enzymes, flavonoids, lipids, and alkaloids as reducing agents. A biodegradable technique produces silver oxide nanoparticles from Prosopis cineraria bark extract. This paper defines a biologically friendly, simple, cost-free, and predictable production of AgO nanoparticles (NP) from Prosopis cineraria aqueous bark extract, as well as their antibacterial efficacy. Silver oxide nanoparticles (NP) were green-produced with a bark extract of Prosopis cineraria, acting as a cap and reducing agent. The XRD study revealed that the AgO NP was in a face-centered crystal structure with a mean crystal size of 69.95 nm. The colour variations were used to detect the silver oxide nanoparticle forms in the extracts, and the successful manufacture of the AgO NP was validated using ultraviolet-visible spectrophotometry, which captured the SPR peak at approximately 601 nm. AgO NP was studied using an SEM to analyse the nanoparticles’ square shape and size. The antibacterial activities of the green synthesis of AgO NP were verified against gram-positive microorganisms like S. aureus, E. faecalis, and S. pneumoniae, and gram-negative microorganisms like E. coli, P. mirabilis, and P. aeruginosa, and the inhibition zones were found. Finally, the AgO NP produced by Prosopis cineraria bark extract is a valuable source of bioactive natural compounds. AgO NP demonstrated our antibacterial properties, which can be employed in future studies using a variety of biological approaches.
