Use of stains to detect fingermarks
Biotechnic and Histochemistry
Detection of fi ngermarks at a crime scene or on related items is of prime interest for forensicinvestigators, mainly for identifi cation purposes. Most of the fi ngermarks are invisible to thenaked eye, however. The application of detection techniques is required to establish visual contrastbetween the secretion residue and the underlying substrate. We give here a review of thefi eld related to the concept of using stains to detect fi ngermarks. A distinction has been madebetween the physically driven classical detection techniques, the chemically driven ones, andthose based on nanostructured materials, an emerging fi eld in forensic science.
