Nanobots

The thought of scientists desiging nanobots that would be able to repair the human body is amazing to me. They could be used to explore your body in order to find out sources of troubles. My husband has underwent exploritory surgery twice and the recovery was a very difficult process. Hopefully in the near future the nanobots will be able to help cure cancer or at least check for spreading. Just thinking about this is unrealistic to me, in my head I catch myself visualizing an R2-D2 robot in combate with a cell! Who would have thought about this 15 years ago.
