Abstract
A cartridge useful in detecting fingerprints includes a housing with a chamber therein and an outlet from the chamber. The chamber contains a thermally stable porous or fibrous support impregnated with both: PA0 1 ) a cyanoacrylate ester, and PA0 2) a volatile, emissive lanthanide metal-complex or actinide metal-complex. Upon the application of sufficient heat to the support, the cyanoacrylate and metal complex volatilize and co-deposit on fingerprint residue to enhance the visualization of the fingerprint.
