Designed to be injected into a human body to create a self defence system that can eliminate nanotech particles. The Beiton Nanotech Corporation developed the Eiton particle as a vaccine to counter potential nanobots attacks to human bodies. These robots do not have communication functions to eliminate the potential of hacking. They are designed with one function in mind: to search and neutralize any harmful particles, including any non-Eiton nanobots in a human body.
They live off a very small amount of human body's nutrients and normally last about 5 years before another shot is required.
