BLEAY, S.M., KELLY, P.F. and KING, R.S.P., 2010. Polymerisation of S2N2 to (SN)(x) as a tool for the rapid imaging of fingerprints removed from metal surfaces. Journal of Materials Chemistry, 20 (45), pp. 10100 - 10102.
Polymerisation of S2N2 to (SN)x on metallic surfaces is induced by interaction with the minute corrosion signatures of removed (by washing) fingerprints; as vapour-phase S2N2 is employed, it follows that the process has the potential to rapidly screen large/convoluted metal pieces, such as explosive device fragments whose prints were wiped by the detonation.
