Nanotech strips are a type of Protoss medical device in and outside combat zones. Basically they are a bunch of preprogrammed nanobots suspended in a thin film for rapid dispersal along the skin. Careful programing must be done by technicians before application or the strips risk becoming hazardous to the user. In most cases, the Nanotech strips are for medical emergencies such as stabilizing patients when teleportation is unavailable. Practically any Protoss going out to battle or exploring deep space carries at least a med pack full of these devices (Predator: Medi-Kit).
