A post-antibiotic era would be terrifying. Luckily, researchers are working on ways to avoid such a dire fate, looking into treatment options that go beyond antibiotics. One of these new research pathways was described this week in a paper published in the journal Nature Biotechnology. The research involves introducing liposomes, small structures that are designed to mimic a cell membrane, into the body. These particular liposomes are designed to act as decoys, drawing bacterial defenses (usually toxins secreted by bacteria) to themselves instead of letting them attack cells within the body. Once the toxins reach the liposomes, they are trapped and can't damage the cells of the infected organism.
