Researchers from the Massachusetts Institute of Technology say they have created a portable device that would manufacture small amounts of medications.
Experts believe this sort of mechanism would be helpful on the battlefield or for doctors working in remote or developing parts of the world.
The device provides a single dose of treatment in a short amount of time that contains a small droplet of cells in a liquid.
It then produces a human growth hormone which aids in wound-healing.
Researchers say the miniature drug-making tool could provide therapies such as vaccines and treatments for conditions such as diabetes or cancer.
