This paper describes the co-precipitation manufacture of magnetite iron oxide nanoparticles (Fe3O4 NPs). Using Fourier Transform Infrared (FT-IR) spectrophotometry, X-Ray Diffraction (XRD), Dynamic Light Scattering (DLS) analysis, and Field Emission Scanning Electron Microscopy (FESEM) equipment, the structure, morphology, and magnetic characteristics of the produced material were described. The FT-IR spectrum offers crucial proof of the magnetite (Fe3O4) nanoparticles’ effective production and provides important details about the functional groups connected to the nanoparticle surface. The Scherer’s Formula determined the average particle size of 15.7 nm based on the XRD result, which showed the existence of Fe3O4 NPs. The XRD pattern matched the reference magnetite (Fe3O4) pattern (JCPDS No.19-0629). The sample displayed a monodisperse distribution profile with a single dominant peak, indicating a homogenous population of particles. The diffraction light scattering (DLS) particle size analyzer revealed an average size of iron oxide nanoparticles. Iron oxide nanoparticles’ cubical to sub-cubical structure, reasonably uniform morphology, and average size of 52.5 nm were validated by characterization of their mean particle size and shape. Fe3O4 NPs’ antibacterial properties were assessed by determining their minimum inhibitory concentration (MIC). Active antibacterial action against bacterial species was demonstrated by Fe3O4 NPs, with MICs values of 25 mg/ml for K. pneumonia and 50 mg/ml S. aureus and E. coli.
