In how many years, the nano-medicines will be available to us?

Answer 1

There are NIH/NCI grants AND developments in nanotech today. There are 4 known centers in the US that are currently in development and/or testing phase for nanotech-based therapies of some nature. So plan on another 10 years before you really see them in action but 4 or 5 years from now start watching NOVA for the first big movers in the field.

Answer 2

If you are refering to nano-machines being used as medical treatments then the answer is at least 20 years before they will even begin testing them... Of course, an astonishing breakthough could occur at any time and greatly decrease that timeframe...
