Antibacterial, efficacy, green fabrication, sonochemical, zincite,


Nanoparticles have made a steady progress in all the branches of science. It is used in biological applications including nanomedicine. Zinc oxide is also known as Zincite generally seen in a crystalline form. Zinc oxide nanoparticles are multifunctional. It has effective antibacterial activity. This study focuses on the synthesis of zinc oxide nanoparticle by the sonochemical and green method, characterized by XRD, SEM and to determine the antibacterial efficacy of green and chemical techniques.

Results prove that green synthesized Zinc oxide nanoparticle shows the enhanced biocidal activity. In addition the current study has demonstrated that the particle size variation and surface area to volume ratio of green synthesized Zinc oxide nanoparticles are responsible for significant high antibacterial activity. From the result obtained it suggested that the biogenic green fabrication is a better choice due to eco-friendliness.
