Just like a regular-sized device requires a regular-sized motor to operate, a nanodevice likewise requires a molecular-scale motor. In some cases, that motor takes the form of a piston, and building a piston that's just a few nanometers long ... well, it's pretty hard. It can and has been done, but it's an extremely fiddly process.
