Abstract:

Detecting physical forensic evidence on a surface includes contacting the surface with a composition, the composition including a rare-earth metal and a chelator. The composition contacting the surface is illuminated with electromagnetic radiation configured to cause the composition to fluoresce in a pattern indicative of physical forensic evidence. The pattern indicative of physical forensic evidence can then be captured. The composition can be made by combining a rare-earth metal, a chelator, and a solvent to form a solution, precipitating the rare-earth metal and the chelator in the solution, and isolating the precipitate of the rare-earth metal and the chelator from a remainder of the solution. The resulting composition includes a porous metal-organic framework of a rare-earth metal and a chelator, where the pores range in diameter from about 0.01 nm to about 50 nm.
