Preparation and Characterization of Ag-Deposited Silica-Coated Fe₃O₄ Magnetic Nanoparticles with Recycling Antibacterial Properties

Abstract:

In this paper, a novel anti-bacterial agent of Ag-deposited silica-coated Fe₃O₄ magnetic nanoparticles was prepared by a template-activated strategy, which possess a silica coated magnetic core and silver nanoparticles on the outer shell. The as-synthesized nanoparticles have been characterized by transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX). The obtained products exhibited dispersibility and high magnetization, which also show a good recycling antibacterial activity, and the antibacterial rates against Escherichia coli was all 100 % for 3 cycles.
