Synthesis, Characterization of Si/Fe2O3 Nanoparticles and their Antibacterial Activity against Staphylococcus aureus and Escherichia coli

摘要

Silicon doped iron oxide (Si/Fe2O3) nanoparticles were successfully synthesized by co-precipitation method at 60 °C with 2-propanol as solvent. The particle size of Si/Fe2O3 nanoparticles measured with transmission electron microscope and dynamic light scattering techniques are nearly same (36.65 nm). The properties of Si/Fe2O3 nanoparticles are different than core shell SiO2/Fe2O3 nanoparticles as they show aggregation and antibacterial properties. Its antibacterial effect was studied against Staphylococcus aureus and Escherichia coli which showed the significant results. The other structural characteristics of the Si/Fe2O3 nanoparticles were analyzed by scanning electron microscope, X-ray diffraction, thermal gravimetric analysis and Fourier transform infrared spectroscopy.
