This is physics at the _nuclear_ level, nothing to do with nanotechnology. en.wikipedia.org
Nanoscale objects are made by moving atoms around. "Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications." i.e. the nanoscale is roughly 10^-9 to 10^-7 m.

Changes in the nucleus, required to change one element into another, require protons and neutrons to be moved around.
en.wikipedia.org
A proton is about 1.5×10^-15 m in diameter. Those extra 6-8 zeros make quite a difference, as much as the difference between the nanoscale and the human scale.

A kind of transmutation occurs in nuclear fission, but this has no relation at all to nanotechnology, and it is something over which we have very little control (I mean in the products).
