Title
(EN) REVEALING LATENT FINGERPRINTS
(FR) RÉVÉLATION DE TRACES LATENTES
Abstract
(EN)
The invention relates to the field of forensics and relates more particularly to a composition for revealing latent fingerprints, a method for revealing latent fingerprints on a substrate and a kit for revealing latent fingerprints. In particular, according to the invention, latent fingerprints can be revealed using fluorescent compounds of the family of 4-bora-3a,4a-diaza-s-indacenes and, as practiced according to the invention, this does not require the presence of heavy equipment. Compared with known solutions based on cyanoacrylate and/or fingerprint powder, the revealing system according to the invention has the advantage of proposing an alternative that is simple to implement, faster, and can be carried out both in a laboratory and at the scene of a crime, indoors as well as outdoors, while allowing compatibility with conventional DNA detection methods.

La présente invention se rapporte au domaine de la forensique et concerne particulièrement une composition de révélation de traces latentes, procédé de révélation de traces latentes sur un support ainsi qu'une trousse de révélation de traces latentes. Particulièrement, la révélation de traces latentes selon l'invention met en œuvre des composés fluorescents de la famille des 4-bora-3a,4a-diaza-s-indacènes, et telle que pratiquée selon l'invention, elle ne nécessite pas la présence d'un lourd appareillage. Comparativement aux solutions connues à base de cyanoacrylate et/ou de poudre dactyloscopique, la révélation selon l'invention à l'avantage de proposer une alternative simple à mettre en œuvre, plus rapide et pouvant être réalisée aussi bien dans un laboratoire que sur une scène de crime, en intérieur tout comme en extérieur, tout en permettant une compatibilité avec les méthodes classiques de détection de l'ADN.
