Simona Frančeze (Simona Francese): Vaši otisci prstiju otkrivaju više nego što mislite

Vaši otisci prstiju otkrivaju više nego što mislite

Naši otisci prstiju nas čine jedinstvenim, ali oni su takođe skladište informacija skrivenih u molekulima koji otkrivaju naše radnje, stil života i rutinu. U ovom fascinantnom govoru, hemičarka Simona Frančeze pokazuje kako proučava ove mikroskopske tragove koristeći masenu spektrometriju, tehnologiju koja analizira otiske prstiju do detalja koji su do sada bili nemogući, i demonstrira kako ova najnovija forenzička nauka može da pomogne policiji u hvatanju kriminalaca.

Fingerprints contain a microscopic world of molecules that reveal much more than just identity. Using advanced mass spectrometry, scientists can now detect traces of drugs, medical conditions, and even products like condom lubricants from a single print. In a dramatic case study, overlapping fingerprints on evidence were separated and analyzed, helping investigators pinpoint both the victim and the likely suspect. This molecular insight is reshaping forensic science and opening new possibilities for criminal profiling.
