Abstract

The Ag-La²O³ hybrid nanoparticles were prepared by loading Ag nanoparticles on the surface of the La²O³ nanorods. The synthesis was a one-step process where sodium borohydride was used as a reducing agent to convert silver ions into silver nanoparticles, which were further deposited on the La²O³ nanorods. Moreover, they were found evenly dispersed upon the surface of La²O³ supports. The as-prepared Ag-La²O³ nanocomposites showed anti-oxidizing and significant antibacterial effect in vitro. Using the results from transmission electron microscope (TEM), the plausible mechanism was also proposed to explain the inhibition of bacterial growth. The present strategy can be potentially extended to develop drug-labels and other antibacterial agents.
