A Start On Biomolecular Nanomachines
(From Medical News Today). It's never too early to start in on the research that will lead to medical nanorobots of the sort envisaged by Robert Freitas. Advanced nanomedicine will take over from regenerative medicine as science progresses further down the path of extending the healthy human life span - but we are only just getting started today. The first research projects into "wet" nanorobotics are all about developing a technology base on which to build therapeutic applications; this is the work of decades, all told. For more information on the likely future of these technologies, you might want to read Chris Phoenix's "Nanotechnology and Life Extension."
