Soon, relatively inexpensive mass spectrometry units could tell police (and doorknob knows who else, with BushCo’s Homeland Security) a lot more about your fingerprints.
Been using drugs? Handling TNT or guns? (Or, maybe, ammonium nitrate?) It could be detected.
R. Graham Cooks, a professor of chemistry at Purdue University, has shown how it could literally detect a fingerprint whorl of cocaine, for example.
But, it could have a more beneficial side.
The newer units could improve cancer detection, especially as an adjunct to other surgery.
