The suitcase contained a very compact little molecular assembler, well up to such simple tasks.

This is the basic assumption of mechanosynthesis which some scientists think will create a molecular assembler.

It turned out that the molecular assemblers were heavy, and tended to sink to the bottom.

The molecular assemblers would also be able to make copies of themselves, so they could multiply into the billions.

Clearly, molecular assemblers are possible in this limited sense.

This article mostly discusses "molecular assemblers" in the popular sense.

This report does not discuss the threat posed by potential so-called "molecular assemblers."

"Are you telling me you've got molecular assemblers on this line?"

A conjoined set of molecular assemblers was slipped into you.

Even if we never build molecular assemblers, the knowledge we'll gain from trying may change the world.
