Chemist contributes to development of novel method for recovering old fingerprints
Date: 10.8.2011
A Northern Illinois University chemist is part of an international team of scientists whose work might someday crack open cold-case files.
The scientists are developing a new fingerprinting method that could make it possible to recover previously unusable or undetected prints from old evidence and from surfaces long considered too difficult by crime scene investigators.
This is the first antibody-based technique that specifically targets amino acids, which are ubiquitous components of human sweat and are present in invisible fingerprints on non-porous surfaces, such as glass and ceramics.
