In the present investigation, we chose the very simple and eco-friendly chemical method for synthesis of zinc oxide nanoparticles from leaf extract of Tamarindus indica (L) (T. indica) and developed the new green route for synthesis of nanoparticles. Formed product has been studied by UV-vis absorption spectroscopy, Photoluminescence (PL) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FE-SEM) and with corresponding energy dispersive X-ray analysis (EDX). Mainly, the present results depicted that the synthesized nanoproducts are moderately stable, hexagonal phase, roughly spherical with maximum particles in size range within 19-37 nm in diameter. The antibacterial and fungal activities of aqueous extracts of T. indica were ended with corresponding disk diffusion and Minimum Inhibitory Concentration (MIC). The highest mean zones of inhibition were observed in the ZnO NPs (200 mu g/mL) against Staphylococcus aureus (13.1 +/- 0.28). Finally, it can be concluded that microbial activity of ZnO NPs has more susceptible S. aureus than the other micro organisms. Further, the present investigation suggests that ZnO NPs has the potential applications for various medical and industrial fields. (C) 2014 Elsevier B.V. All rights reserved.
