This sounds remarkably similar to Theranos.
It's conceivable they discovered this methodology and told the wrong people.
None the less, because we're hearing about this now means it's already obsolete and being replaced by something else.
... or you just have to convince investors you can do such a thing. Remember Theranos? The incentive to claim this knowledge would be powerful, especially for a power mad government. Refer also to FBI crime lab fake bite mark, fiber, and bullet ballistic analysis.
If you are on a jury and you are presented with this (((evidence))) you are right to reject it and send the accused home. You are fucked with an NPC jury, though.

They have them for sale
That's just talking about those naked scanners at the airport.
These are nothing like that
They sure have them now because I got flagged for explosives last time I flew. It detected fertilizer on me from when I was gardening earlier that day.

They have them deployed that can detect traces of drugs or gun powder on your clothes to what you had for breakfast to the adrenaline level in your body in airports now?
