NASA Working on implanted Biocapsules for multi-year treatment on demand

Gizmodo – The NASA Biocapsule—made of carbon nanotubes—will be able to “diagnose” and instantly treat an astronaut without him or her even knowing there’s something amiss. Dr. David Loftus is the man who invented the NASA Biocapsule and has been awarded a patent for it. Loftus said we could be using Biocapsule on Earth within 10 to 15 years

One of the primary threats in space is exposure to high levels of radiation. When astronauts travel beyond Low Earth Orbit (i.e., to the Moon or Mars), they are at risk of acute radiation exposure from “solar particle events,” sudden releases of intense radiation from the sun, which can damage bone marrow and wipe out someone’s immune system. That’s where the NASA Biocapsule kicks in: It could be filled with cells that sense the increased levels of radiation and automatically disperse medicine to help the body compensate.

This isn’t science fiction. We already use a hormone called G-CSF (Granulocyte colony-stimulating factor) to treat cancer patients who are receiving radiation treatment. So it was a very small jump to put these cells in a capsule. Without G-CSF, an astronaut’s immune system might not recover; he or she could die of a massive infection.

The Biocapsules aren’t one-shot deals. Each capsule could be capable of delivering many metred doses over a period of years. There is no “shelf-life” to the Biocapsules. They are extremely resilient, and there is currently no known enzyme that can break down their nanostructures. And because the nanostructures are inert, they are extremely well-tolerated by the body. The capsules’ porous natures allow medication to pass through their walls, but the nanostructures are strong enough to keep the cells in one place. Once all of the cells are expended, the Biocapsule stays in the body, stable and unnoticed, until it is eventually removed by a doctor back on Earth.

While the treatment of radiation-effects in space is NASA’s no. 1 application for the Biocapsule, different capsules will be created to combat different threats. Heat, exhaustion, and sleep-deprivation are serious risks on an EVA (a “spacewalk”), and astronauts are usually on a very tight schedule. Different capsules can be created that contain unique triggers and treatments for different stress-factors. Naturally, DARPA has expressed a huge interest in the Biocapsules for potential military applications. But there are far loftier things planned for us Earthlings.

On our home planet, the NASA Biocapsule’s primary target is diabetes—specifically, patients who need insulin.
