The phytochemical components of Leucas cephalotes were used in this study to create zinc oxide nanoparticles (ZnONPs) sustainably, and antibacterial investigations have all been used to characterize the ZnO NPs. A wurtzite hexagonal structure with an average crystallite size of 15.03 nm is revealed by XRD investigation. The zinc oxide nanoparticles' shape and elemental composition were investigated using SEM and EDX techniques. The ZnO nanoparticles' tetrapod-like structure was discovered through morphological investigations. FT-IR spectroscopy provided additional evidence that the nanoparticles' stabilizing functional groups are present. A study of UV-visible absorption revealed a 3.53 eV band gap. The antibacterial activity of ZnONPs was found to be significantly influenced by variations in their size and surface area-to-volume ratio. The positive diffusion method was used to evaluate ZnONPs' antibacterial activity. The findings demonstrated ZnONPs' strong broadspectrum antibacterial capability by inhibiting the development of yeast and both Gram-positive and Gramnegative bacteria.
