The present study was conducted to prepare cost effective and environment friendly zinc nanoparticles
(Zn NPs) by using ZnSO47H2O and extract of sesame seeds. Zn NPs were characterized by using scanning
electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffraction and
antibacterial potential was checked by using disc diffusion method. Solution colour turned yellow which
ultimately confirmed the formation of Zn NPs and seed extract was used as a reducing agent. Crystalline
size of the NPs was revealed by XRD spectra i.e. 9.07 nm. Functional groups were identified by the FTIR.
SEM analysis given idea about the spherical shape of NPs. Antibacterial activity of the Zn NPs against different
bacteria (S. pneumoniae, P. aeruginosa, E. coli and S. aureus) was measured by inhibition zone which
ranged from 3.3 to 12.6 mm.
