Hydrothermal synthesis of zinc stannate nanoparticles for antibacterial applications

Abstract

A facile and economical hydrothermal method was used to synthesise Zn2SnO4 nanoparticles with cubic spinel structure. The crystallography and optical properties of the as-synthesised nanoparticles were studied using X-ray diffraction (XRD) and UV–visible spectroscopy (UV–vis). The morphology of the nanoparticles was observed using field emission scanning electron microscopy (FESEM). The synergistic antibacterial effect of Zn2SnO4 nanoparticles against Gram-positive and Gram-negative pathogenic bacteria was investigated. These results indicate that the Zn2SnO4 nanoparticles have potent antibacterial activity against both Gram-positive and Gram-negative bacteria and can be used as a bactericidal agent to prevent and control the spread and persistence of infectious diseases.
