Magnetic Janus nanorods for efficient capture, separation and elimination of bacteria

Abstract

Magnetic Janus mesoporous silica nanoparticles (MSNs) with CTAB-loading and amino-functionalization were prepared through a one-pot synthesis strategy. Janus MSNs exhibit outstanding bacterial capture and separation performance, enabling the highly efficient elimination of both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, illustrating their application potential in biomedicine.
