Fingerprints on Paper Detected using Heat

Two University of Technology, Sydney students develop a method which relies on the application of heat to the sample, with the fingerprint development accomplished in a matter of seconds

The method developed by the two students relies on the application of heat to the sample, with the fingerprint development accomplished in a matter of seconds. "This was an interesting approach, as originally the aim was to make fingerprints colored using chemicals, but the students noticed that the application of heat alone could actually develop fingerprints," said Dr. Brian Reedy, a senior lecturer and member of the Center for Forensic Science in the Faculty of Science.
