Nanotrites

 'Tiny, molecular 'robots' injected into a host organism, capable of enhancing or or suppressing a wide range of biological functions' -

Nanotrites are the super-science of the 2040's. The symbiotic microcomputers preserve the body of their host and struggle to 'repair' it after injury. They were discovered by Anton Kvasir in 2039, an American scientist working on Earth. Before long they were used in Armed Forces Elite Troops, too repair their after injury. They can also be used to repair bodies in Medical Procedures after large injuries or treating some forms of cancers.

In some Armed Forces Elite Troops the nanotrites can activate a defribrillator which keeps the user alive and active, it also sends out a pulse of electic energy which stuns any organisms in the vicinity.
