Abstract

In this present study the non toxic CuS nanoparticles was synthesized by the reaction of copper acetate, thiourea along with the precipitating agent NaoH under chemical precipitation method. The final product CuS nanomaterial was dried at room temperature for better growth of nanoparticles. The size and growth of the crystal depends on the temperature also on the addition of reagent. The resultant nanocrystal were characterized using various techniques like X ray diffraction reveals the particle size, Scanning electron microscope determines the morphology of crystal, Energy dispersive X ray spectroscopy investigate the elemental composition of nanoparticles, U-Visible spectroscopy examine the presence of metallic ion, Fourier transform infrared spectroscopy inspect the existence of functional group. The antibacterial activity of hexagonal structured copper sulphide nanomaterials against gram positive and gram negative bacteria were also analyzed for their wide applications.
