well, Femtotechnology is a term used by some futurists to refer to structuring of matter on a femtometer scale, by analogy with nanotechnology and picotechnology. This involves the manipulation of excited energy states within atomic nuclei (see nuclear isomer) to produce metastable (or otherwise stabilized) states with unusual properties. In the extreme case, excited states of the individual nucleons that make up the atomic nucleus (protons and neutrons) are considered, ostensibly to tailor the behavioral properties of these particles (though this is in practice unlikely to work as intended).
The most advanced form of molecular nanotechnology is often imagined to involve self-replicating molecular machines, and there have been some very speculative suggestions that something similar might in principle be possible with "molecules" composed of nucleons rather than atoms. For example, the astrophysicist Frank Drake once speculated about the possibility of self-replicating organisms composed of such nuclear molecules living on the surface of a neutron star, a suggestion taken up in the science fiction novel Dragon's Egg by the physicist Robert Forward.
