Abstract

Spinel ferrite nanoparticles (SFNPs) have high demand in the field of electronics and medical engineering. The properties of these spinel ferrites are greatly influenced by the synthesis techniques and their parameters. The spinel ferrite nanoparticles (SFNPs) of Mg0.2Zn0.5Mn0.3Fe2O4 were successfully prepared using hydrothermal route at 180 °C for 15, 20 and 25 hrs duration. The effect of processing duration on structural, magnetic and antibacterial behaviour were recorded by XRD, FTIR, TEM, EDS, VSM and Gouy’s balance. The cubic structural morphology with space group Fd-3m confirms spinel nature of prepared nanoparticles recorded by TEM and XRD. The multidomain superparamagnetic nature of synthesized nanoparticles were observed by magnetic parameters from smooth S shaped M-H curve of VSM. Antibacterial efficacy of SFNPs against different pathogenic bacteria were demonstrated using Zone of influence (ZOI).
