Week 7 - Cyanoacrylate Fuming

I have decided to take my research project in a different direction but still focus on fingerprinting within the forensic field. I have decided to concentrate on Cyanoacrylate fuming. Cyanoacrylate, also called super glue, fuming is a chemical method for detecting latent fingermarks on non-porous surfaces such as glass, plastic, etc. The technique relies on the deposition of polymerized cyanoacrylate ester on residues of latent fingermarks. This method leaves a white residue where the latent print develops when conducting this method. 

In my experiment, I want to find out what material is best to use this method when looking for latent prints. I will be using the materials stone, metal, wood, plastic, glass, paper, and leather. To tell which material records the best data, I will be taking my latent print using carbon black powder and identifying multiple points on minutiae.

Minutiae points are the major features of a fingerprint image and are used in the matching of fingerprints. The minutiae points are used to determine the uniqueness of a fingerprint image. 

Once I have my fingerprint minutiae points, I will then compare the findings to the latent print developed using Cyanoacrylate fuming to see if those points are easily matchable between the different types of material I am testing.
