The study is to focus at the evaluation of the potential of the antibacterial activity of the synthesized Zinc oxide nanoparticle using Leptadenia hastata leaf extracts on selected bacterial; E.coli, S. aureus, K. pneumonia. Zinc oxide (ZnO) nanoparticles synthesised, UV, SEM and FTIR were used to characterise the nanoparticles. The particles were further subjected to evaluation of their antimicrobial activity. The FTIR studies was observed to have shown the several chemical functional groups, while the SEM results showed the synthesized nanoparticles were in the range below 100 nm and the size of the particles was slightly ellipsoidal as well as spherical. From the result it was observed that the synthesised nanoparticles have showed significant antimicrobial potentials against the gram negative and gram positive bacteria’s (E. Coli, S. aureus and K. Pneumonia. This study being the first using Leptadenia hastata leaf extract should provide a new agent toward the fight of resistance bacterial and effective therapies in the field of medicine.
