This process builds up a picture, or chemical photograph, and allows for the most comprehensive information obtained from a fingerprint.
"The combined operational advantages and benefits for forensic scientists of tape lifting prints and spectroscopic imaging really maximize the amount of information one can obtain from fingerprints. Our trials show that this technique could play a significant role in the fight against crime," Kazarian was quoted as saying.
The information, in many cases, is enough to determine valuable clues about a person beyond the fingerprint itself, it could potentially identify traces of items people came in contact with, such as gunpowder, narcotics and biological or chemical weapons, according to the scientists.
Chemical clues could also highlight specific traits in a person as a strong trace of urea, a chemical found in urine, could indicate a male, and weak traces of urea in a chemical sample could indicate a female. And specific amino acids could potentially indicate whether the suspect was a vegetarian or meat- eater.
Kazarian speculated about the possible future benefits of this process, saying in the courtroom of the near future, chemical images could feature as key evidence.
He expressed the hope that their work could assist law enforcement authorities to bring dangerous criminals to justice.
