The Israel Police will adopt a new technology to detect latent fingerprints developed by female students from the High School of Arts and Sciences in Jerusalem

The experiment was presented to Superintendent Aharon Franco and Chief of Police Dr. Ezi Zadok who were impressed by the scientific capabilities and hoped that the cooperation with the students from the high school would help improve the image of the police

This week, the Israel Police received a significant reinforcement in the investigation of crime scenes from an unexpected source: two students from the High School for Sciences and Arts in Jerusalem, from the foundation of the Association for Excellence in Education, developed in cooperation with MZP (forensic identification laboratory) a technology that significantly improves the process of detecting fingerprints at the crime scene.

The extensive knowledge of the high school students for science and arts in the fields of science and mathematics allowed them to conduct experiments in the field of forensic identification. From a study they conducted it emerged that some of the components of a fingerprint are amino acids. In such a case, the accepted method is to develop the prints by immersing them in a ninhydrin solution that reacts with the amino acids, and the print is colored purple. In a test done with a spectrophotometer, it was found that the intensity of the obtained color (absorption) with the addition of manganese chloride is 20% higher than the intensity obtained without the manganese. In the research it was found that this improved development method, which uses manganese chloride, enables a better quality development of the fingerprint. With this method it is possible to distinguish many details that were not seen using the previous method. This makes it easier to identify the source of the fingerprint.

After the presentation of the experiment, the police representatives signed a joint agreement with the Association for Excellence in Education.
"I will make the necessary effort so that we can use this amazing discovery." This is what Dr. Ezi Tzdok, head of the Deputy Chief of Police, said at the event. "I welcome the cooperation and believe that it will help the students in developing their scientific abilities and the police in improving its image." 

Hizki Arieli, CEO of the Association for Excellence in Education reinforced his words and said that "I am proud that through education for excellence we were able to contribute to the work of an essential body such as the Israel Police and to Israeli society in general. Projects of this type prove that investing in diversity pays off for everyone."
