Unlocking the Unique Chemical Signatures of Tires Could Aid Forensic Investigations

Unlocking the Unique Chemical Signatures of Tires Could Aid Forensic Investigations

The University of Central Florida team used laser-induced breakdown spectroscopy (LIBS) on each sample. The technique focuses a laser onto the tire sample, which creates a microscopic plasma that emits light according to the chemical elements present. The spectroscopy comes in because it analyzes this light and matches it to the corresponding chemicals. It's the same technique that instruments aboard the Mars rovers (Curiosity and Perseverance) use to determine what kinds of elements are found within the rocks of Mars.
