In this work, Chromium substituted nickel ferrites with general composition NiCr_xFe_2-xO₄&nbsp;(x= 0, 0.25, 0.5, 0.75, 1) were prepared using sol gel auto combustion method. The structural characterization of the samples was carried out using X-ray diffraction (XRD) which confirmed the presence of single-phasic spinel structure and energy dispersive X-ray (EDX) spectroscopy analysis confirmed the presence of all ions as per the stoichiometric ratios.&nbsp; Surface morphology of the samples has been investigated using Field Emission Scanning Electron Microscope (FESEM). The bandgap of the prepared samples was measured using UV-Visible-Diffuse Reflectance Spectroscopy (UV-Vis-DRS Spectroscopy). The antibacterial properties of the prepared compounds were tested against gram-positive and gram-negative bacterium and found that antibacterial property decreased with increase in concentration of Chromium for gram-positive bacteria.</p> V N Archana Jeevan Johns T R Anilkumar Shilpa J Chethalen Anju Ganesh Copyright (c) 2025 V N Archana, Jeevan Johns, T R Anilkumar, Shilpa J Chethalen, Anju Ganesh https://creativecommons.org/licenses/by/4.0 2025-01-14 2025-01-14 3 1 03 06 10.61779/jasetm.v3i1.1
