N2 - Two seizures of counterfeit 100 US$ bills related to the same indicative
number were submitted for processing of latent fingerprints. On one
group of notes, identifiable fingerprints could be detected by the
routine application of amino acid reagents. In the second case, this
technique gave no results, even on deliberately deposited prints.
Fingerprints could be revealed, however, by cyanoacrylate fuming
followed by magnetic powder. Comprehensive paper analysis showed that
banknotes from both seizures differed remarkably by chemical composition
as well as paper macroscopic properties. The difference in surface free
energy (related to surface tension) of the banknotes in the two groups
seemed to be the major factor responsible for the great variance in
fingerprint detectability.
