主 题：Antibacterial Activity Green Synthesis ZnO Nanoparticles Lawsonia inermis
摘 要：In the present study, mehendi extract (Lawsonia inermis) was used for phytosynthesis of ZnO nanoparticles using 0.1 M Zn(NO3)2 as precursor under alkaline condition using NaOH with vigorous stirring for 2 h. ZnO NPs obtained were characterized by UV-Vis spectroscopy, XRD, SEM and TEM that showed change in shape and size. Hexagonal particles were formed due to plant extract relative to the rod shaped particles in absence of plant extract. Further the antibacterial property of ZnO NP synthesized by green method was more effective than those synthesized in absence of plant extract. The antibacterial activity study of both the synthesized ZnO nanoparticles reveals that the nanoparticles synthesized using mehendi extract are more effective than the particle synthesized without mehendi extract. Thus, the use of leaf extract as capping agent would improve the antibacterial property of ZnO nanoparticle. However, bacteriocidal effect of these nanoparticles varies with respect to the organism tested.
