Naši prstni odtisi nas delajo edinstvene, so pa tudi dom svetu informacij, skritih v molekulah, ki razkrivajo naša dejanja, življenjski slog in rutine. V tem navdušujočem govoru kemičarka Simona Francese pokaže, kako preučuje te mikroskopske sledi z uporabo masne sprektrometrije, tehnologije, ki analizira prstne odtise v nekoč nepredstavljive podrobnosti, in prikaže, kako lahko vrhunska forenzična znanost pomaga policiji ujeti kriminalce.

Vaši prstni odtisi razkrivajo več, kot si mislite

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.
