Antibacterial activity of Fe-doped Cd2SnO4 nanoparticles against staphylococcus aureus and salmonella typhi



Metal oxide nanoparticles are capable of successfully inhibiting bacterial strains. Among the several transition metal atoms, iron (Fe) looks to be a viable dopant since iron oxide has been used a lot in biomedical research due to its biocompatibility and magnetic properties. In order to boost its antibacterial activity and facilitate the entry of nanoparticles into bacterial cells, Cd2SnO4 has been selectively doped with Fe. The chemical precipitation method was used to synthesize Cd2SnO4 and Fe-doped Cd2SnO4 nanoparticles toward antibacterial activity. To the best of our knowledge, there is no report is available on the antibacterial activity of undoped and Fe-doped cadmium stannate nanoparticles against salmonella typhi. The nanoparticles formed are in the cubic phase, according to the XRD results, the size of the crystallites is seen to grow as the increase in Fe concentrations. By using the good diffusion method, the antibacterial properties of synthesized nanoparticles were examined against two human pathogens, including staphylococcus aureus and salmonella typhi. Both undoped and Fe-doped Cd2SnO4 nanoparticles have antibacterial action that inhibits pathogen growth, according to antibacterial tests, which have shown the presence of a zone of clearing surrounding the well.
