Doctors are running out of effective antibiotics, as bacteria evolve ways to evade one drug after another. Now DARPA has called for alternatives to conventional antibiotics. Nanotechnologist Chad Mirkin discusses one such weapon–tiny globs of DNA and RNA that can switch off the bugs’ antibiotic resistance. Nanotechnologist Chad Mirkin discusses next-generation antibiotics that target a bacterium’s DNA.
