405 nm light is emerging as a safe alternative to UV light for light-based continuous inactivation of drug resistant bacteria in high risk environments (i.e., hospitals). LED manufacturers are introducing 405-nm room lighting solutions for this purpose. However, inactivation efficiencies of commercial 405-nm technologies are still few orders of magnitude lower than those of UV light. Here, we achieve light 500-fold increased inactivation efficiencies with 405-nm light using radiatively coupled aluminum plasmonic nanoantenna arrays and demonstrated nearly complete deactivation of bacteria (%99,995). Our inactivation scheme opens door to continously self-cleaning surface coatings killing multi-drug resistance bacteria using ambient/room lighting.
