Nanotech

Nanotechnology involves the use of nanites.

Nanites are microscopic machines, often smaller than individual human cells, that can repair or enhance biology at the cellular level. The nanites are injected into the tissue along with the raw materials needed for the upgrade. The nanites then consume these raw materials while constructing the enhancements.

Nanites are a fairly diverse class of machines, and designs vary. Most make use of body heat or chemicals for the power needed to function. Nanites can be used to enhance existing organic systems, construct interfaces between organic components and technology, or replace functions that were previously performed by organic components.

Nanotech is the basis for most forms of Bioware, and virtually all forms of Cyberware.
