Nanograin

Nanograin (N-Grain) is a surveillance capability developed by the Nanotech Unit (BRL-15) for the Strategic Intelligence Office (SIO). It consists of an aerosolised solution of nanobots programmed to act as an optical sensor and audio sensor. Once dispersed, the N-Grains stick to all surfaces in the room and establish complete surveillance coverage of the perimeter. N-Grains are virtually undetectable via the vast majority of counter-surveillance methods.
