Optimisation of Fingermark Detection Methods for the Improved concurrent Recovery of Explosive Residues

Project Member(s): Roux, C., Spindler, X.

Start year: 2015

Summary: The conventional application of fingermark detection methods, including amino acid reagents (e.g. indanedione, ninhydrin), cyanoacrylate fuming, and luminescent stains, can compromise the subsequent recovery and analysis of explosive residues. Earlier research has shown that methods can be developed to increase the recovery of explosive residues. The overall objective of this Research Project is to develop the best methods for visualising fingerprints so that explosive residues can be recovered from them and analysed after development of the fingerprints. The outcome would be a recommended protocol for fingermark detection on items likely to be contaminated with explosive residues. This improved protocol would minimise the loss of explosive residues so that these can be recovered and analysed after items have been processed for latent fingermarks.
