| description | The aim of this study is to find out about the antibacterial activity of a variety of ZnO nanostructures, along with their derivative nanoparticles (ZnO NPs) and nanorods (ZnO NRs) against numerous clinic strains of Gram-negative Escherichia coli (E. coli), Salmonella typhi (S. typhi), Pseudomonas aeruginosa (P. aeruginosa) as well as Gram-positive Streptococcus pneumonia (Strept. pneumonia) bacteria. ZnO NPs and ZnO NRs were efficiently synthesized by using sol-gel and hydrothermal strategies, respectively. Various properties, consisting of the morphology, structure and optical, had been described by using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) as well as ultraviolet-visible (UV-Vis) spectroscopy analysis. This check was performed in Mueller-Hinton agar. The impact of different particle sizes and morphologies of ZnO nanomaterials on the growth of bacteria was measured. In the antibacterial assay, each type of ZnO nanostructure showed effective inhibition. The findings showed that ZnO NRs exhibited more efficient antibacterial activity than that of ZnO NPs agents. This was once the case for both Gram-positive and Gram-negative bacteria. Hence, the study indicated that the antibacterial of ZnO NRs against Strept. Pneumonia was similar to those for S. typhi. However, depending on the particle size effect of ZnO nanostructure, it was found that ZnO NPs showed much less antibacterial activity towards S. typhi than ZnO NRs did. |
