Healing Stones – Part 2: Targeted Cancer Therapy

How do you get a nano-robot to target and kill just cancer cells but leave healthy cells alone?

Think like a suicide bomber:

  1. Carry a concealed mass killing weapon like a bomb,
  2. Act and look like you belong,
  3. Get into the enemy’s site, and
  4. 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.
