Interactions between latent fingermarks, deposition surfaces and development agents
… uniqueness and lifelong permanence. Latent fingermarks represent by far the most evidentially common and challenging form of deposition, whereby an invisible copy of the unique friction ridge fingertip pattern is left as an amalgamated secretory residue on any surface that is touched. Dry …

Analysis of the composition of latent fingermarks by spectroscopic imaging techniques.
Despite the success of DNA fingerprinting, fingermarks remain an efficient means of ascertaining the identity of an individual at many crime scenes. There are numerous enhancement techniques used to develop fingermarks on a range of deposition surfaces. Despite this, there is a need for further …

Synthesis, characterisation and application of novel quinones for the detection of latent fingermarks
Identification of an individual through fingermarks is one of the oldest types of evidence in forensic science. A number of techniques are available for the detection of latent fingermarks on porous surfaces; for example 1,2‐indanedione zinc (IND‐Zn), 1,8‐diazafluoren‐9‐one (DFO), and ninhydrin. …

Fingermark Enhancement on Metallic Surfaces
The recovery of latent fingermarks from surfaces is critical in the investigation of a crime scene. It could provide the identity of a victim of the crime or a person of interest to the investigation. The surfaces being examined may comprise of a single or mixture of materials, each requiring a …

Enhanced techniques for fingermark recovery from fabrics
Fingermarks have been used for centuries as a means of determining an individual’s identity and fabrics have long been considered a difficult substrate from which to visualise and collect fingermarks. This study mainly concentrated on vacuum metal deposition (VMD) and cyanoacrylate fuming (CAF), to …

Improved detection of human involvement in avian wildlife crime
… were found to accelerate the degradation of fingermarks as they age, with precipitation having the greatest impact on their successful development. This was particularly evident for natural fingermarks whose predominantly water-soluble composition left them more susceptible to outdoor …

The effects of the surface properties of thermal paper on fingermark visualisation
… forensic practitioners have in developing latent fingermarks on thermal paper, e.g. receipts, whereby the standard method either causes blackening of the paper or a large volume of acetone has to be used to wash the receipts to remove the dyes prior to mark enhancement resulting in a loss of …

Applications of UV-visible spectral imaging in forensic science
… and without chemical enhancement, and for latent fingermarks after chemical enhancement. Focus was on substances whose spectrum exhibited a steep change in absorbance or fluorescence over a small wavelength range. Substances with such spectral features were able to be enhanced using arithmetic …
