If it were real, this explosion would be super small, but that doesn't stop it from being a tremendous bomb on an atomic scale. Why make such a tiny explosive? For now, it was mostly a demonstration in seeing what could be done. The researchers acknowledge that the nano-explosives field is new, waiting for breakthroughs, and it needs working tiny bombs before people can even start to figure out how to use them. A possible use could be, of course, destroying very small things. One idea calls for carbon nanotubes filled with water to be inserted into cancer cells and then heated up with lasers until they explode, functioning as a nanobomb that damages only the harmful tissue. Buckybombs, with their great explosive potential, could be an even deadlier weapon in a war against cancer, viruses, or bacteria, where their tremendous force and small size destroy small targets and leave the rest of the human intact.
