ABSTRACT:
A method for developing latent fingerprints includes placing an apparatus in an area having one or more objects. The apparatus has a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber of a housing containing a cyanoacrylate catalyst and being adapted for emitting vapors. The housing is impregnated with the cyanoacrylate catalyst or has a layer of cyanoacrylate catalyst on a portion of its interior surface. The apparatus optionally has a breakable capsule breaking mechanism for assisting a user in breaking the breakable capsule within the housing. The user breaks the breakable capsule, causing the cyanoacrylate monomer spilling from the breakable capsule to react with the cyanoacrylate catalyst contained in the housing to create vapor fumes. The vapor fumes contact an object being tested to reveal any latent fingerprints on the object.
