This study presents the environmentally friendly synthesis of Citrus sinensis bio-mediated Zinc Oxide (ZnO) nanoparticles. The characterization techniques, including XRD, UV Visible spectroscopy, and FTIR, provide insight into the structural and optical properties of the synthesized nanoparticles. The determined average crystalline size using the Debey Scherrer equation is 15.57 nm, highlighting the nanoscale nature of the particles. The band gap energy of the sample was measured as 3.26 eV through UV-Visible spectroscopy. Furthermore, the antibacterial efficacy of the synthesized ZnO nanoparticles was assessed against Salmonella typhimurium, Staph. Aureus, S. faecalis, and E. Coli, using modified Kirby-Bauer disc diffusion method. The findings suggest the potential of these nanoparticles as effective antibacterial agents.
