Abstract

Lumicyano is a new reagent used to reveal fingermarks on non-porous and semi-porous surfaces. It can be applied in trace visualization process instead of cyanoacrylate and fluorescent dyes (in the case of nonabsorbent surfaces) or cyanoacrylate and dactyloscopic powders (in the case of semi-porous surfaces). Fingerprints are revealed in the traditional cyanoacrylate fuming chambers. The present work, the effectiveness of Lumicyano was investigated, in comparison to previously used sequences of laboratory techniques, i.e. cyanoacrylate + Basic Yellow 40 and cyanoacrylate + Black Ruby dactyloscopic powder.
