Wide application of nanoparticles stimulates the need for synthesizing them But, the conventional methods are usually hazardous and energy consuming. This lead to focus on “green synthesis”of nanoparticles which seems to be easy efficient and ecofriendly approach. In this study the green synthesis of zinc oxide nanoparticles was carried out using root extract of Rubia Cordifolia a reducing agent and their antimicrobial activity against various bacterial pathogens. Zinc oxide nanoparticles are known to be one of the multifunctional inorganic nanoparticles with effective antibacterial activity. Microbiological tests were performed using varying concentrations of green ZnO NPs with size 14.18 nm. Green synthesized NPs showed antibacterial activity against Micrococcus luteus, Staphylococcus aureus, Escherichia coli. Zinc Oxide nanoparticles were characterized by XRD, SEM, EDX and TEM. The green synthesis of Zinc Oxide nanoparticles appears to be cost effective, eco-friendly and easy as compare to other methods for the nanoparticles synthesis and its antibacterial activity.
