SYNTHESIS AND CHARACTERIZATION OF Ag, Fe3O4 AND COMPOSITE Ag-Fe3O4 NANOPARTICLES

Popis výsledku v původním jazyce

The aim of the present work is to prepare composite Ag-Fe3O4 nanoparticles. Many kinds of nano-sized antibacterial materials such as TiO2, ZnO, MgO, chitosan, copper and silver have been reported elsewhere. Among them, nanocrystalline silver was proven to be the most effective antimicrobial agent, since silver and its compounds have powerful antimicrobial capability and broad inhibitory biocidal spectra for microbes including bacteria, viruses and eukaryotic microorganism. Fe3O4 with strong magnetic properties and low toxicity can be heated to the elevated temperature in an external alternating magnetic field. This inductive heating property of magnetite is successfully used for localized hyperthermia treatment of cancer, hence only the local tumor region is heated without damaging the surrounding healthy tissues. In this work relatively monodisperse silver-coated Fe3O4 nanoparticles were produced by reducing silver nitrate on the surface of Fe3O4 nanoparticles. Thereby bifunctional na
