The health of men being sent to space has always been a huge concern for space organizations, and NASA has come up with a solution that borders on the edge of being a miracle. NASA has made the NASA Biocapsule – a tangle of carbon nanotubes that will be used to contain particular cells and even medicinal substances inside it. It’s tiny, inserted into the skin, non-reactive, fast-acting and virtually indestructible!
How it works
This is how this contraption works – A small incision is made on the body of the astronaut, barely skin deep. The nanotube, along with whatever package it is wrapped around, is then inserted subcutaneously. The wound is then either stitched up with a couple of stitches and the astronaut is good to go!
The Biocapsule has been made by Space Biosciences Division at NASA Ames, like all other medical technology made exclusively for NASA. Dr. David Loftus has been awarded a patent for leading the group, which came up with this creation.
The Biocapsule might contain cells, which can dispense hormones should the body require it. For example, if one is diabetic, or if one develops such a condition during a long stay in outer space, the capsule might contain pancreatic islet cells (or some cells which behave like these). Should the body need insulin, the cells will detect the low amounts in the blood and automatically start secretion. Dr. Loftus explains:
The capsule would contain pancreatic islet cells (from animals) or would contain engineered cells designed to behave like pancreatic islet cells, with both glucose-sensing and insulin secretion function. Patients with low-insulin requirement might benefit from implantation of a single capsule (containing perhaps a million to 10 million cells); patients with higher insulin requirement might require implantation of more than one capsule.
The Biocapsules can handle diseases as serious as radiation sickness. The Biocapsules can be used to contain cells that release the hormone G-CSF (Granulocyte colony-stimulating factor), which is a standard treatment for cancer patients undergoing radiation therapy so that they don’t develop any side-effects. Cells capable to detecting high exposure can be planted inside these Biocapsules and these will discharge the G-CSF hormone when triggered by the high radiation dose.
The Best Aspect of it all!
Now here is the coolest aspect of this miracle – it can be easily used on Earth! This is a potential explosive keg of medical revolution having the size of a few microns. It can save millions of lives on Earth, were it to go public! This might even be used to administer very local dosages of substances, which might be harmful to other organs, if it spreads.
With the closest doctor being a few thousand kilometers away, the tiny bundle of security might be the life of an astronaut. Literally!
