Nanotechnology

Nanotechnology is defined as "the art of manipulating materials on the molecular or atomic level especially to build microscopic devices" (or robots).(Merriam Webster Online) Modern science fiction literature uses these devices (commonly referred to as "nanotech") for various purposes inside the human body such as: repair, maintenance, and enhancement. Possessing nanotech however does not normally constitute a cyborg as this modification is typically not enough to cause a noticable difference in appearance that is usually associated with cyborgs.
