Universal Assembler

A molecular assembler is a construction machine that manipulates and builds with individual atoms or molecules. One of the prime goals of long-term nanotech research is the production of a programmable self-replicating assembler. This is a device which can make a complete copy of itself given raw materials and energy. After sufficient quantities of assemblers are available, they are then re-programmed to produce something else useful. In science fiction literature, such assemblers have been called matter compilers.

Assemblers capable of making any object desired are called universal assemblers. Nature abounds with nanotechnological self-replicating assemblers called bacteria, which can be reprogrammed to perform some types of tasks by genetic engineering. Some progress has been made in this area, where researchers have inserted genes for a particular protein into a bacterium. One of the first examples of this is the immune-system hormone interferon.
