Detection of residues from explosive manipulation by near infrared hyperspectral imaging: A promising forensic tool

Highlights • NIR-HSI is used for the analysis of explosive residues on human handprints. • PLS-DA classification model is used to identify the explosive residues. • Ammonium nitrate, blackpowder, smokeless gunpowders and dynamite were used for PLS-DA construction. • A methodology is able to detect blackpowder, smokeless gunpowders or dynamite residues. • NIR-HSI as a fast, non-destructive and non-contact promising forensic tool.
