Abstract
Increasing interest for the biosynthesis of metal nanoparticles is under investigation, mainly due to their wide biomedical applications and research interests in nanotechnology. Mentha asiatica and Ocimum basilicum leaf extracts were used to evaluate their extra-cellular potential synthesis of silver nanoparticles and their bactericidal impact on different kinds of pathogenic bacteria. UV-Vis spectroscopy was utilized to monitor the formation of silver nanoparticles. X-ray diffraction (XRD) analysis of the formed silver nanoparticles revealed a structure of spherical and cubical shapes with different planes (range 111-311 planes). Scanning electron microscopy (SEM) was used to characterize the morphology of the nanoparticles obtained from plant extracts. The synthesized nanoparticles were found to be active against clinically isolated human pathogens, Staphylococcus aureus and Escherichia coli. Our work proffers an eco-friendly method for biogenic silver nanoparticle production. This could provide a faster synthesis rate comparable to those of chemical methods, and could potentially be used in areas such as food and medical applications.
