  That’s a great idea! I think we kind of already do for some diseases. The nano bots are made from viruses made in a lab. The virus has a chemical in it that should help make someone better. Its called gene therapy and its already been used! This only works when a disease is genetic though.
  
  Maybe in the future we would have different things that can go inside the body and heal people with other sicknesses?
