title: A hybrid antioxidizing and antibacterial material based on Ag-La2O3 nanocomposites.
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.
