Nanoscale analysis of the interaction between cyanoacrylate and vacuum metal deposition in the development of latent fingerprints on LDPE
Vacuum metal deposition (VMD) has been previously demonstrated as an effective development technique for latent fingerprints, and in some cases has been shown to enhance prints developed with cyanoacrylate (superglue) fuming. This work utilises scanning electron microscopy (SEM) to investigate the interactions of the two development techniques when applied to latent fingerprints on low density ...
متن کاملThe detection of drugs of abuse in fingerprints using Raman spectroscopy II: cyanoacrylate-fumed fingerprints.
This paper describes the application of Raman spectroscopy to the detection of exogenous substances in cyanoacrylate-fumed fingerprints. The scenario considered was that of an individual handling a substance and subsequently depositing a contaminated fingerprint. These fingerprints were enhanced by cyanoacrylate fuming, a process in which a layer of white cyanoacrylate polymer is deposited on t...
متن کاملDeveloping Methods to Improve the Quality and Efficiency of Latent Fingermark Development by Superglue Fuming
The completed research program was designed to provide fundamental information that can be used to improve the superglue fuming method of developing latent fingermarks, by optimizing the acquisition of developed latent fingermarks and enhancing the quality of aged fingermarks. This has been realized by, first, using our expertise in polymer chemistry to explain the role of temperature on the su...

متن کاملLumicyano™: a new fluorescent cyanoacrylate for a one-step luminescent latent fingermark development.
Latent fingermarks developed by cyanoacrylate fuming often lack contrast; therefore further enhancement is required, such as dye staining. This second step is part of the conventional detection sequences performed by forensics practitioners. Dye-staining or powder dusting aims at improving contrast and at increasing the legibility of details, yet their use may at times be limited. Indeed powder...
