It's called "DNA Fog." The device fills a room with smoke to confuse an intruder. The smoke isn't just to make it hard for the person to see; it also contains droplets loaded with DNA. If the person escapes, they are still covered with it, and it's invisible.
As far as the DNA is concerned, “the material is identical” to human DNA, he said, “though there is a different sequence of components.” Much of the spray’s effectiveness, he said, comes from the mystique surrounding DNA.
“No one really knows what it is,” he said. “No one really knows how it works.”
At this McDonald’s the DNA liquid is contained in an orange box the size of a large paperback book, mounted over an entrance door. “You don’t smell it; you don’t see it; nobody knows it’s there,” said Jean-Paul Fafie, who has managed the McDonald’s for the last 12 years.

Thanks to technology, being a criminal just got that much harder. Just as stolen money can be rigged with exploding dye packs, Applied DNA Sciences has developed a mist called smartDNA that can be used to covertly spray criminals during illegal activities, such as a break-in, so that they can be later identified by police.
The DNA in the mist spray consists of artificially engineered gene sequences that act like bar codes. As a single strand of DNA with 20 base pairs in the mist can have over a trillion unique combinations, no two mists would be alike. Every tagging device would have its own unique sequence. Once sprayed, the DNA molecules attach onto a perpetrator’s clothing, shoes, hair and skin, as well as any stolen objects. The water-resistant genetic material is very difficult to wash off and lasts about two weeks.
Should a suspect be arrested, police would swab them and then read the sample using a process called polymerase chain reaction. This amplifies the genetic material, making it easy to spot. The overall process is inexpensive enough that even non-specialists could oversee it. As DNA evidence generally stands up well in court, criminals caught with traces of the mist could be prosecuted based on what the crime scene left on them.
- insert joke about monica lewinsky time there already was another kind of dna spray...
The Applied DNA Sciences spray is already being successfully used in Sweden and has begun to be rolled out to businesses in the U.S.

- fibertyping, dna inks, varnish, laminates, metal coatings with custom dna sequences
- THE ABSOLUTE CERTAINTY OF DNA - inventoried in cloud, DNA at its core - Should there ever be a question about the validity of a digitalDNA code, a laboratory-based analysis can be conducted to determine authenticity.
