New Uses for DNA Identification

It’s now possible to synthesize a nearly infinite number of unique DNA sequences. It’s also possible to identify the sequence of even a small sample of DNA quickly and cheaply. Taken together, these two advances are likely to lead to some interesting new uses of DNA technology.

According to an article in The New York Times, in Rotterdam, the Netherlands, police are experimenting with synthetic “DNA sprays” as a way to discourage robberies or to catch robbers of local businesses. When a store is robbed, the store clerk activates a security system that sprays the robber with a fine mist containing a unique synthetic DNA sequence as the robber departs. The system also notifies police that a robbery is in progress. Suspects who are apprehended within a certain time frame can then be tested for that specific DNA sequence.

Another idea: “DNA crayons” - each with a different DNA sequence - to mark valuable items that belong to you. Items suspected of having been stolen could then be tested and returned to their rightful owners. We’ll probably hear about other practical uses of DNA technology in the future. Have YOU got any good ideas?
