The method involves a vapor wand capable of developing cyanoacrylate fingerprints in about 20 seconds. The vapor wand heats rechargeable cartridges of cured cyanoacrylate and emits a stream of vapor that can be used in fume hoods, normal fuming chambers, or open-air environments. The wand is about the size of a pen and, when operated with a proprietary 3M sublimation dye in the cartridge, yields fluorescent fingerprints in one step. In addition, a vapor pump has been designed for larger applications. The covolatilization of a subliming 3M thermal dye with cyanoacrylate has been successful in consistently tagging latent fingerprints on all surface types. Further research into the styryl dye family is recommended, since the material sublimates readily and develops with cyanoacrylate monomers to form a resist specific to fingerprint residue. While this phenomenon primarily occurs in the vapor stream, higher dye material concentrations produce coverage throughout a chamber. 7 figures
