Forensic scientists in the U.K. used Raman spectroscopy to identify lipstick smears from crime scenes without direct contact, protecting the integrity of the evidence. "Continuity of evidence is of paramount importance in forensic science and can be maintained if there is no need to remove it from the bag. ... For forensic purposes, Raman spectroscopy also has the advantages that microscopic samples can be analyzed quickly and non-destructively," said Michael Went, researcher of the study in the journal Analytical Methods. Lipstick traces can be used to document contact between a victim and a suspect or to document the presence of a person at a given location.
