Development and Application of Small-molecule Spatial Distribution Imaging: Laser Ablation Direct Analysis in Real Time Imaging-Mass Spectrometry (LADI-MS)

The applicant proposes to use laser ablation coupled with mass spectrometry to nondestructively extract additional evidence from evidence gathered at a crime scene. This technique has potential applicability to multiple types of forensic evidence, including fingerprints, ammunition and questioned documents. As an illustrative example, this technique, if successful, would extract and identify the molecules associated with explosive residue captured in the chemicals used to develop fingerprints, without destroying the prints.
