Abstract

A facile one-pot synthesis of Ag@Fe2 O3 core-shell and Ag-Fe2 O3 heteromer nanoparticles is developed, and the core-shell nanoparticles show superior antibacterial properties compared to their heteromer counterparts and plain Ag nanoparticles. The mechanism for the increased efficiency is proposed to be due to the enhanced Ag ion release from the iron oxide shell-protected pristine Ag surface.
