Ans.D. Hard Evidence
- Cyanoacrylate, also called super glue, fuming is a chemical method for the detection of latent fingermarks on non-porous surfaces such as glass, plastic etc.
- The method relies on the deposition of polymerized cyanoacrylate ester on residues of latent fingermarks.
- The method develops clear, stable, white coloured fingerprints. However, several post-treatment procedures can be used to improve the contrast of developed prints.
- In addition to it, some pre-treatment procedures can also be used to develop aged latent fingermarks. It is an efficient, non-destructive and excellent procedure for developing latent fingermarks.
