The main advantage of the synthesized nanoparticles of diameter 29 nm was that the sample could be prepared by using of cheap precursors in a cost effective and eco-friendly manner. Structural, morphological and chemical composition of the prepared nanoparticles were investigated by X-Ray Diffraction(XRD),Scanning Electron Microscopy(SEM) with energy dispersion X-ray dispersive fluorescence spectroscopy (EDAX). The antimicrobial effects of the zinc sulphide (ZnS) nanocrystals were studied by spot inoculation technique and also by well diffusion technique against twelve pathogenic bacterial strains. Nanoparticles of ZnS showed antimicrobial activity against both Gram positive and Gram negative strains except Shigella sonnei.
