A thin film material which prevents nanotic devices from affecting it, or penetrating it.

So-called 'true nanobar' is utterly immune to such activity, however most products marketed or represented as nanobar are not so resilient. These lesser products are everything from hyperslick materials ("Goo just slides right off!"), to wearable blue-goo defenses, to surprisingly inert compounds.

There are groups of people who are actively involved in researching and trying to trace the origins of some of the more effective nanobar products. Some are found to be mere marketing ploys, others serious efforts, and yet others artistic expressions of one kind or another.
