How have nanotechnologies made advances in medicine?

Question

What are some examples?

Answer 1

The business I own through Arbonne International uses nanotechnology as a means to allow their products to penetrate through the skin, allowing the creams to absorb better for healthier softer skin.

..and thats just one example of nanotechnologies!

Answer 2

To be honest, nanotech is an extremely young technology.  I'm not sure we can actually say that it exists yet, since we are not able to fabricate machines on the nanometer level, and as a consequence we have not been able to make self replicating nano machines which is the ultimate step forward (think the gray goo).  There are some chemicals which may be advertised or labeled as nano tech in medicine but truly we have not yet advanced to that point.
