Photoluminescent lead detection in gunshot residue (IMAGE)
Caption
Photoluminescent lead detection in gunshot residue. (A) Shooting firearms produces gunshot residue that typically contains lead particulates. (B) Methyl ammonium bromide in the reagent reacts with lead in gunshot residue to form perovskite, which emits bright green light upon illumination with UV light. (C) Typically, the combustion plume and bullet wipe contaminate objects such as clothing, hands, and targets with gunshot residue, which is rapidly visualized with photoluminescent lead detection to assess suspect involvement and to assist crime scene reconstruction.
