The New York Times reports that in Europe, a "new system involved an employee-activated device that sprays a fine, barely visible mist laced with synthetic DNA to cover anyone in its path, including criminals, and simultaneously alerts the police to a crime in progress. The mist — visible only under ultraviolet light — carries DNA markers particular to the location, enabling the"": police to match the burglar with the place burgled. Now, a sign on the front door of the McDonald’s prominently warns potential thieves of the spray’s presence: “You Steal, You’re Marked.”"
Something similar is offered to banks in Europe and possibly the US. They can purchase special red dye packs to sneak into bank robber's take. Not only do they explode and dye the robber and his money (rendering it useless), but each has a unique DNA tag linking it to the crime.
