Is this possible within the future nanotechnology ?

Question

Do you think its possible within the future if nanomachines were injected into the blood stream they could be programmed to regenerate damage done to the body, prevent cancer, prevent disease and improve on what we already have inside us?

Answer 1

Yes, theoretically it is possible.

Physicists and bioengineers already have the materials and technology to build nanomachines.

However, governments and financial institutions have, so far, failed to support nanotech, which prevents it from being promoted at the moment. This might be due to ethical prejudices, ignorance, or merely financial reasons.
