Synthesis of Iron Oxide–Tin Oxide Nanoparticles and Evaluation of their Activities against Different Bacterial Strains

Nanoparticles were found having applications in various fields of life but recently in diagnostic and therapeutic fields of medicine. Iron oxide-tin oxide (Fe2O3-SnO2) nanoparticles were synthesized via hydrothermal method with various concentrations of sodium dodecyl sulfate (SDS) surfactant. Their characterization was done by Fourier Transform Infrared Spectroscopy (FT-IR), Thermogravimetric Analysis (TGA), Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) powder techniques. Antibacterial activities of these metal oxides nanoparticles were determined and they were found active against gram-positive B. subtilis and B. lichniformis and gram-negative E. coli, P. aeruginosa and K. pneumonia.
