Abstract
The nickel nanoparticles have been fabricated by laser ablation of pure nickel (99.99%) target in liquid environment. Three different liquids, i.e., de-ionized water, sodium dodecyl sulphate (SDS) and ethanol have been used to control the size of nanoparticles. The size of nanoparticles has been measured by zetasizer nano zs using dynamic light scattering (DLS). The size range is found to be 43 nm to 80 nm in de-ionized water, 24 nm to 32 nm in ethanol and 4.5 nm to 5 nm in SDS. The surface morphology of the nickel nanoparticles have been observed by atomic force microscope (AFM). Structural characteristics of the nanoparticles are confirmed by X-ray diffraction technique; showing (111), (200), (400) peaks of fcc nickel nanoparticles and (200), (222) peaks of hcp nickel nanoparticles. Also (311) peak of NiO nanoparticles was found. The various concentrations of nanoparticles produced are confirmed by UV-Vis spectrometer. The bactericidal effect of the fabricated Ni nanoparticles is checked against well known bacteria Escherichia coli . The nickel nanoparticles have been found highly toxic against Escherichia coli
