How do you get a nano-robot to target and kill just cancer cells but leave healthy cells alone?
Think like a suicide bomber:
- Carry a concealed mass killing weapon like a bomb,
- Act and look like you belong,
- Get into the enemy’s site, and
- Blow it up.
Nanotechnology for medicine does not necessarily mean robotic machinery. On the nanometer scale, the mechanism is more like a virus and can better be characterized by bio-chemistry. A nano-scaled robot uses molecular keys (cell targeting ligands) and special polymers (diblock copolymers) instead of gears and cogs.
This video explains it best:
So what are the healing stones? They are theoretical first-aid nano-bot factories and delivery systems. See other “Healing Stone” articles for more information.
Of all the future technological breakthroughs noted on this site, I hope this one comes first.
