Recent advances in the chemical imaging of human fingermarks (a review)

Abstract: This review highlights the considerable advances in the chemical imaging of human fingermarks that provide more chemical information, including numerous endogenous and exogenous constituents. Despite remarkable development in DNA analysis and recognition, human fingermark analysis remains one of the priority approaches available for obtaining reliable forensic evidence. Additional information about the donor can be obtained from the chemical composition of latent fingermarks in addition to the ridge pattern, s… Show more

“…Moreover, they often encompass hyperspectral imaging, that is, the image contrast is governed by spectral information from each pixel. Thus, by using vibrational spectroscopy (Raman and IR), it is from spectral uniqueness, or the “chemical fingerprint”, possible to identify foreign compounds in the FM . In this respect, IR hyperspectral imaging has been used to study FMs contaminated with residues from cosmetics and drugs, as well as chemical degradation (aging) of latent fingerprint residues in a controlled environment .…”

“…[ 31 ]. Sebaceous glands excrete sebum fluid, which is mainly composed of fatty acids, glycerides, cholesterol, squalene and a variety of lipid esters [ 32 ]. As the relative hydrophobic secretions of the sebaceous LFMs exist, candle soot nanoparticles which are generated from the centered flame are more likely to adhere to the hydrophobic ridges rather than the furrows and the bare glass substrates, which enhanced the spatial pattern of the LFM remarkably.…”

“…Since such FM is mostly not visible, they are then referred to as latent fingermarks (LFM). LFMs are usually not visible to the naked eye and need to be enhanced for forensic applications (Wei et al, 2016).…”
