Abstract

Gunshot residue (GSR) are solid particles produced when a firearm is discharged, and its detection is important evidence in forensic investigations. Currently, SEM-EDS is the standard technique adopted for the analysis and identification of GSR, however this methodology is inefficient for lead-free ammunition. Herein, we report the inclusion of high photoluminescent Metal-Organic Frameworks in ammunition to allow for the visual detection of GSR. The tests indicated that marked GSR is easily visible in proportions above 5.0 wt%. One gram of marker suffices to tag one hundred .38mm bullets or sixty-two .40mm bullets.
