so the saying 'great minds think alike' is true then
yes the reasons that i came up with this idea is that these nanos could add significant medical support to the body, and run for a significantly
longer period than battery powered nanos
potential uses (depending on the state of medtech at the time):
improved healing time
support for antibodies against viruses, disease, bacteria
cell regeneration in vital organs, and other sensitive areas (eyes, ears etc.)
nano surgery is a fascinating concept, but it may be many years away
