Polycrystalline spinel nickel ferrite nanoparticles were prepared by employing sol–gel auto combustion method. The as-prepared nanoparticles were characterized using XRD and FTIR for structural characterization, the morphology of the samples was analyzed from the FESEM micrographs. The XRD analysis validated the cubic spinel structure of the synthesized NiFe 2 O 4 nanoparticles. The octahedral and tetrahedral locations of metal oxide bands were proven by two prominent metal oxide bands in the FTIR spectrum at 466 and 589 cm −1 , respectively. The prepared nanoparticles are in spherical morphology, according to the FESEM analysis. The optical properties exhibited by the NiFe 2 O 4 nanoparticles was examined by studying UV–Vis spectroscopy and photoluminescence spectra. The magnetic properties were studied at room temperature by employing VSM analysis. Agar well diffusion tests procedures were used to assess the bactericidal effect of nickel ferrite particles. Using Dalton’s Lymphoma Ascites cells, the nickel ferrite nanoparticles were investigated for short-term in vitro cytotoxicity. The presence of NiFe 2 O 4 inhibits Bacillus subtilis and Klebsiella pneumonia growth.
