Is the development of nanotech in medicine being suppressed by the pharmaceutical companies?

If we could inject ourselves with single-cell sized robots that could be programmed to do anything, wouldn't that make all medication obsolete? All the theory, and most of the technology is there. It's just a matter of putting in the cash. By the way, this would cure AIDS also. Your thoughts?

Nanotechnology like single-cell sized robots, are popular in science fiction, but beyond today's technology. Many research efforts are under way, but thousands of inventions and developments will need to happen before they become a reality.

The theory may be there, but the theory doesn't buy you anything. How many decades from the theory of a jet engine to the first jet fighter?

Some technologies that need to be developed: very small motors, very small computers, very small optical or chemical sensors, assembly of molecular scale devices.

Once it gets close, be assured that the pharmaceutical companies will be working hard to make it a reality. They would love to be able to sell it to you.

No it isn't being suppressed. The latest advances in nanotechnology are nowhere near advanced enough to do anything useful at all. People have made items like a motor, gear or actuator, one at a time. A robot requiring many thousands of components that can travel in the bloodstream and identify and zap the AIDs virus seems like it will stay in the realms of sci-fi no matter how much cash you throw at it.
