Forensics Europe Expo London 2016

Welcome to Forensics Europe Expo

<!– –>Forensics Europe Expo is the only international event dedicated to forensic technology. The event combines a high-level conference and seminar programme with an exhibition of specialist equipment in applications across all areas of the forensic sector.

Now in its 4th remit, this year’s event is expected to grow considerably with more global exhibitors showcasing the latest innovations to an audience of senior buyers and specifiers. The unique aspect of this event is the active collaboration across multiple industry sectors from scene of crime products and digital forensics to lab equipment and forensic analysis.

The co-location of the conference and supporting seminar programme creates a key learning environment with the opportunity to network and develop good business relationships as well as see products and services in action.

Forensic Focus

The unique quality of this event is active collaboration between all sectors that use forensic science in their daily professional life, sharing their knowledge, case studies and innovative techniques. Forensics Europe Expo will take you on a journey starting at the scene of crime and finishing in the courtroom.

Identifying Gender From a Fingerprint

(Shutterstock)Fingerprints have been the standard in identification for more than a century. But even as other biometrics are being looked at to identify individuals, researchers are continuing to look for ways to pull more information from the unique patterns and traces left behind by a touch.

Race, and exposure to drugs and explosives have been the focus of recent studies. But now, even gender can be determined from the concentration of amino acids in a fingerprint, according to the latest study published by a University at Albany team in the journal Analytical Chemistry.

Heating the fingerprint surface to 40 degrees Celsius forced the amino acids to separate out of the print, according to the researchers. Then the sample was analyzed with a chemical dye that oxidized to a telltale color based on the concentration of amino acids.

Since females have more amino acids, the test proved 99 percent effective, the team concludes.

“It provides a quick male/female response and can be performed on-site,” the team writes. “These results can narrow down the possibilities in a suspect pool in a quick and timely manner when there is not matching fingerprint image or DNA profile in the corresponding databases.

“Furthermore, this type of analysis can potentially be utilized by any and all members of law enforcement with no need for specialized training, as it works in a similar manner to pregnancy strips or glucometers,” they add.

Jan Halamek, lead author, told Forensic Magazine by email that the next experiments would be implementing methods to pull the amino acids from fingerprints on random surfaces, and to also deploy the chemicals directly to the fingerprint at the scene. One would be a portable, strip-like device, he explained. Proof-of-concept papers are in the works, he added.

Use at actual crime scenes would depend on funding, and getting law-enforcement partners, Halamek added.

Other teams have looked to the details in fingerprints to potentially help determine commonalities among drug users, ethnic groups, and other identifying factors.

A National Institute of Standards and Technology team found it could determine trace levels of drugs in fingerprint residue using mass spectrometry, in a study published in May.
The whorls and ridges of a fingerprint pattern could be used in the future to determine race and ethnic group, according to a study published in September.

The controversial study maintains that much more work needs to be done to complete a database of the pattern differences, however.
