In deciphering how nanotechnology works, considering the three dimensions, The second dimension deals with the:

Passive and static objects i.e., nanoparticles that have properties different bulk objects, even if they have the same composition; active devices i.e., those that can store information, induce energy, or change their state and the nanofacture, which refers to atomically precise manufacturing (APM), i.e., collection of instruments and procedures.
