Fingerprint and inkjet-trace imaging using disulfur dinitride.
Exposure of fingerprints to S(2)N(2) vapour results in the prints being visually imaged by polymeric (SN)(x) on an unprecedented range of media; in addition, the polymer forms in response to the interaction of S(2)N(2) with traces of inkjet inks, for example the minute amounts left by the contact between printed paper and an envelope.
