"Spicy world of NanoScience"
Productive NanoSystems, form molecules to super-products:
A nano-factory is a proposed system in which nano-machines (resembling molecular assemblers, or industrial robot arms) would combine molecules to build larger atomically precise parts. These, in turn, would be assembled by positioning mechanisms of assorted sizes to build macroscopic (visible) but still atomically-precise products. >>
A functioning nanofactory could create virtually any product at the cost of only the input raw material and energy.>>
