Anyone bold enough to ignore warning signs and break into (or bust out of) the sandwich shop will be coated in a fine mist of synthetic DNA. The spray is “traceable for weeks” and is “only visible with a glow under ultraviolet light,” according to the newspaper report:
In most cases so far, Larsen said once police see the glow, people confess. If they don’t, a laboratory can match the spray to the specific store to tie someone to the crime scene.
The adhesive liquid can be applied to valuables, and like the intruder spray, has a unique synthetic DNA code. Property owners register their SelectaDNA kits and then, if items are stolen, police can use the DNA liquid to find owners.
