Use of stains to detect fingermarks

摘要: Detection of fingermarks at a crime scene or on related items is prime interest for forensic investigators, mainly identification purposes. Most the are invisible to naked eye, however. The application detection techniques required establish visual contrast between secretion residue and underlying substrate. We give here review field concept using stains detect fingermarks. A distinction has been made physically driven classical techniques, chemically ones, those based nanostructured materials, an emerging in science.
