Uneori, în cazul unor decese suspecte, hainele sunt singurele
obiecte de la „locul
crimei” pe care există
indicii revelatoare de tipul amprentelor digitale.
O tehnică nouă, dezvoltată de Universitatea Abertay, Marea
Britanie, împreună cu Poliţia Scoţiană, permite identificarea unor
amprente pe ţesături, prin depunerea, în vid, a unor straturi
foarte fine de aur şi zinc.
Metoda, folosită deja pentru detectarea amprentelor pe
suprafeţele dure, a fost adaptată pentru a putea fi utilizată şi în
cazul materialelor textile.
