International. A forensic team in the United Kingdom is using a new mass spectrometry technology that could help solve unsolved crimes, according to a press release.
The machine, developed by the University of Nottingham, shoots ions at an object to create a "map" of the substance it finds, such as sweat. It produces constant and reliable results and does not damage the existing evidence, since current methods for making a copy of fingerprints are not good enough and DNA analysis can damage the evidence.
The machine detects fragments of the fingerprint substances and can form a pattern on a computer that interprets the findings as a recognizable fingerprint, which can help in cases where fingerprints are difficult to recover. Scientists say he can make copies without damage.
