High-performance magnetic antimicrobial Janus nanorods decorated with Ag nanoparticles

Silver nanoparticle-decorated magnetic-silica Janus nanorods, synthesized by an environmentally friendly in situ approach, show superior magnetic sensitivity, strong affinity binding to bacteria, and highly effective and long-term antimicrobial activity against bacteria. Such antibacterial nanomaterials could have great potential in biomedical applications due to their excellent biocompatibility and non-hemolytic property.
