Abstract

Fingerprints have been the constant since the birth of mankind. The cyanoacrylate fuming method, also referred to as the super glue method, is proven to be the most effective tool used by investigators to develop latent fingerprint on non-porous surface such as glass and plastic. This method uses the vapors of superglue to develop latent fingerprints. The method relies on the deposition of polymerized cyanoacrylate ester on residues of latent fingerprints. This method develops clear, stable, white colored fingerprints on glass surface till upto 5th week whereas on plastic surface it was upto 4th week when observed under the temperature ranges between 12℃-25℃ at different time interval.
