Chimistul Sergei Kazarian, de la London Imperial College, a pus la punct o procedura care permite identificarea unor minuscule reziduuri chimice pe amprentele digitale.
Acestea trebuie recoltate cu ajutorul unui benzi speciale, impregnate cu un gel care, spre deosebire de metodele traditionale, pastreaza urmele originale.
Apoi banda este trecuta printr-un dispozitiv cu raze X, care-i traseaza harta chimica.
“In cadrul proceselor viitorului, imaginile chimice vor putea fi admise ca probe. Iar aceasta tehnica va juca un rol decisiv in combaterea criminalitatii”, a explicat Kazarian.
