Green synthesis of metal nanoparticles is an interesting and expanding research area due to the potential applications for the ecofriendly development of novel technologies. Generally, nanoparticles are prepared by a variety of chemical and physical methods which are yield environmentally benign wastages largely. Present study reported a simple, convenient and low cost method for the synthesis of manganese nanoparticles by reducing manganese acetate with the help of easily available natural products viz., lemon extract as reducing agent and turmeric curcumin as a stabilizing agent. The curcumin was isolated from turmeric by using solvent extraction method and used for manganese nanoparticle stabilization. The characterization of curcumin and manganese nanoparticles was done by using UV- Vis and FT-IR spectroscopic techniques. The morphology of manganese nanoparticles was confirmed by SEM and TEM techniques. The size of MnNPs was in the ranges about 50nm. The antimicrobial activities of synthesized Mn nanoparticles were observed higher antimicrobial activity than the standard drug against S. aureus, C. lunata and T. simii and also exhibited similar inhibition activity to standard drug against E. coli, C. albicans, and A. niger.
