We combined silver and iron oxide nanoparticles to make unique Ag@Fe2O3 yolk–shell multifunctional nanoparticles by the Kirkendall effect. After the surface functionalization using glucose, the Ag@Fe2O3–Glu conjugates exhibited both high capture efficiency of bacteria and potent antibacterial activity. The Ag@Fe2O3 yolk–shell nanostructures may offer a unique multifunctional platform for simultaneous rapid detection and capture of bacteria and safe detoxification treatment.
