On Demand Drugs

Researchers at MIT and other institutions have created tiny freeze-dried pellets that include all of the molecular machinery needed to translate DNA into proteins, which could form the basis for on-demand production of drugs and vaccines.

The pellets, which contain dozens of enzymes and other molecules extracted from cells, can be stored for an extended period of time at room temperature. Upon the addition of water and freeze-dried DNA, the pellets begin producing proteins encoded by the DNA.
