Photosensitizer and Vancomycin-Conjugated Novel Multifunctional Magnetic Particles As Photoinactivation Agents for Selective Killing of Pathogenic Bacteria

Novel multifunctional magnetic particles (MMPs) conjugated with photosensitizer and vancomycin were fabricated by surface modification of Fe3O4 particles. The capacities to target, capture and inactivate pathogenic bacteria and good biocompatibility suggest that the MMPs have great potentials as photodynamic inactivation agents for serious bacterial contamination.
