A modified Super Glue® technique - the use of polycyanoacrylate for fingerprint development

Latent fingerprints on various items were developed by exposing them to fumes obtained by heating the solid polymer, polycyanoacrylate. The results were comparable in quantity to those obtained by the regular Super Glue® technique, based on the liquid cyanocrylate monomer which is harder to handle. Without heating, the development process required much longer periods of time. Two simple devices have been constructed that use the new technique.
