Nanotech

Nanotech is necessary to make Cyberware work. Without nanotechnology, there would be no functioning DNI. Nanites route electrical signals into the right nerve, nanocircuits compute a translation, and this allows the street samurai to move at lightning speed, the decker to hack, the rigger to rig, and so on. But nanotechnology can do much more. In addition to its various other applications in augmentation technology, it can be an augment itself - as Nanoware. This usually refers to a nanite colony that migrates freely in the bloodstream or body plasma of a wearer, and makes them more capable in some way, or supports cyberware like a vehicle control rig in its function. These colonies are washed out or broken down over time - unless you implant a nanite breeder that reproduces them, of course.
