Agnirva Space Premier League - Expedition #31320: Harnessing Microgravity for Precision Drug Delivery: The Microencapsulation Electrostatic Processing System

Imagine tiny capsules delivering medicine precisely where it's needed in the body. That’s the promise behind the Microencapsulation Electrostatic Processing System (MEPS), an experiment conducted during Expedition 5 on the ISS.

Led by Dr. Dennis Morrison of NASA's Johnson Space Center, MEPS tested a technique for producing microcapsules under microgravity conditions. These capsules can be used to enclose pharmaceuticals, enzymes, or even living cells, offering controlled release and targeted delivery.

Microgravity offers a unique manufacturing advantage: it allows more uniform and stable capsules to form, since the disruptive effects of gravity are minimized. The MEPS used electrostatic forces to control the encapsulation process, forming spherical microcapsules suspended in a fluid medium.

The findings from this experiment showed that space-produced microcapsules had higher uniformity and improved wall structure compared to those made on Earth. These results open new doors for space-based pharmaceutical manufacturing, especially for drugs that are difficult to produce with high precision on Earth.

This technology also has potential applications in cancer treatment, hormone therapy, and chronic disease management. By producing high-quality drug delivery systems in orbit, we move one step closer to personalized medicine that’s both effective and efficient.
