Drones tag and track quarry using nanoparticle sprays

Abstract:
The US Air Force is funding work to let drones tag suspects or cars with a spray that gives them a distinct spectral signature, making them easy to track.

Voxtel's taggants are based on quantum dots - semiconductor nanocrystals less than 50 atoms across. Because of quantum effects, they absorb and emit light at specific wavelengths. The company has demonstrated a taggant powder that, when illuminated with an invisible ultraviolet laser, can be detected by infrared cameras 2 kilometres away. The powder is delivered as an aerosol that clings to metal, glass and cloth, and batches can be engineered to have distinct spectral signatures.
