Chemical functionalising, attaching functional groups to the surface of your
discrete MEMS/NEMS part. By bringing such differently functionalized parts into
proximity of your reaction site (e.g. by shuttling them on a plane surface) 
you'd do chemistry by numeric control (mechanosynthesis).

Both silicon and CNTs are easy to functionalize.

While direct writing as a pure top-down technique scales from macro to nano,
you can also combine top-down and bottom-up (such as functionalizing ~nm parts).
