| Summary, etc. |
The extensive use of antibiotics has accelerated the emergence of antibiotic-resistant<br/>bacteria, presenting a major threat to public health. This study explored an alternative<br/>antimicrobial strategy through the green synthesis of Zinc oxide Nanoparticles (ZnO<br/>NPs) using Clitoria ternatea L. leaf extract. The calcined zinc oxide nanoparticles yielded<br/>48.7%. ZnO NPs were characterized using several techniques. UV-visible<br/>spectrophotometry showed an absorbance peak at 304 nm, confirming ZnO NP<br/>formation. FTIR analysis revealed peaks at 1435 cm−1 (C=O), 1146 cm−1 (C-O), 880 cm−1<br/>(C-H), and 419 cm-1<br/><br/>(Zn-O). SEM and TEM images indicated hexagonal and spherical<br/>morphologies with an average size of 41 nm. EDS analysis confirmed the elemental<br/>composition with zinc and oxygen accounting for 30.49% and 47.56%, respectively.<br/>XRD patterns confirmed the crystalline nature of the nanoparticles. Despite successful<br/>synthesis and detailed characterization, the antibacterial activity of ZnO NPs, assessed<br/>using the Disc Diffusion Method, showed no inhibitory effect against Gram-positive<br/>Staphylococcus aureus and Gram-negative Salmonella typhi. These findings suggested<br/>that further optimization of the synthesis process or additional functionalization of ZnO<br/>NPs might be necessary to enhance their antimicrobial properties. While the potential of<br/>green synthesis methods was evident, the challenges in developing effective<br/>nanoparticle-based antibacterial agents were also underscored.<br/>Keywords: Clitoria ternatea L., ZnO NPs, antibacterial efficacy, Disc diffusion method,<br/>Staphylococcus aureus |
