The people who are commenting that this is not something that could be used in a real-world situation are absolutely right. However, that's not what it's for - it's a study to determine whether the basic principles might be workable at all.
There would be much more work required before it could be applied in practice.
One confusion is about how this might be used. It's about the possibility of a very cheap and readily-available means of basic testing (not a substitute for laboratory testing) in criminal investigation.
