This raises the possibility, and many times actuality, of using phages to treat bacterial infections that are no longer treatable with antibiotics. But bacteria can evolve resistances to viruses as well as drugs, and using multiplying, evolving entities as treatments in people raises questions about the safety and consistency of the treatment. This study circumvents these questions by using phages for delivery and targeting of bacteria rather than the therapeutic agent itself. The actual treatment is done with tiny rods of gold, gold nanorods, bound to the phage surfa
