Voxdot™ Nanotaggant Systems
Voxtel’s nanocrystal taggants are deployable in solvents, inks/paints, and aerosols, allowing them to be easily integrated into various applications — such as Combat Identification (CID), Material Control and Tracking, Identification of Friend or Foe (IFF), and Tagging, Tracking, and Locating (TTL) — and customized for the unique needs of other operations.
Leveraging our combined expertise, we offer customized end-to-end systems: taggant delivery systems combined with optical interrogation and detection systems.
Update 2010-04-09: Voxtel has recently published a paper discussing considerations in nanocrystal taggant system design, and reviewing Voxtel’s own developments in versatile taggant formulation and km-range standoff detection.
Voxtel’s low-cost methods of manufacturing Voxdots™ allow multi-kg quantities of high-quality nanocrystals to be delivered at very reasonable prices. Our corporate experience, which ranges from military electro-optical systems engineering to detector development and nanophotonics, is rare and hard to come by. Our experience allows us to work with our customers to develop concepts of operation, and to identify spectral bands and atmospheric windows for optimal deployment.
Voxtel has two classes of Voxdot™ nanotaggant: transparent and pigmented. These classes can be used separately or together.
Transparent Nanotaggants
Voxtel’s transparent nanotaggants are optically clear and, upon UV stimulation, emit in the VIS–NIR–SWIR. These taggants are stimulated in the ‘solar blind’ portion of the UV spectrum, so they do not emit upon solar exposure. The taggants can be specified to respond to UVA–UVC (below 400 nm), UVB–UVC (below 315 nm), or only UVC (below 266 nm) laser radiation.
Pigmented Nanotaggants
Voxtel’s pigmented nanotaggants are not optically transparent, but can be activated by laser radiation or other light sources in the UV, VIS, or NIR portions of the optical spectrum. These nanotaggants can be tuned to emit in 50 nm wavebands anywhere in the VIS–SWIR spectral region.
