Abstract

The high incidence of infectious disease and increase in the incidence of antibiotic resistance has led to the application of inorganic nanoparticles as novel antimicrobial agents owing to their unique physical and chemical properties. The present study reports the synthesis and antimicrobial activity of MgFe2O4 and Co0.8Mg0.2Fe2O4 nanoparticles (NPs). The NPs were synthesized using the low temperature combustion synthesis and the synthesized NPs were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive absorption spectroscopy (EDAX). The synthesized NPs exhibited good antimicrobial activity against Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), Staphylococcus aureus (S. aureus) and Serratia marcescens (S. marcescens). Co0.8Mg0.2Fe2O4 NPs showed higher zone of inhibition than MgFe2O4 NPs for E. coli and S. aureus with a minimum inhibitory concentration of 2.5 mg/ml as compared to gentamicin as standard antibiotic. The relatively large zone of inhibition exhibited by Co0.8Mg0.2Fe2O4 on E. coli and S. aureus suggests its potentials in the treatment of infections commonly associated with these microorganisms.
