“…A variety of other ninhydrin‐positive substances have been identified in eccrine sweat (such as cysteic acid, methionine sulphoxide, and glucosamine; Liappis & Hungerland, 1973), as well as proteins including albumin, cathepsin D, dermicidin, immunoglobulins (IgG, IgA, IgD, and IgE), keratins 1 and 10, and antimicrobial proteins and peptides (Drapel, Becue, Champod, & Margot, 2009; Flad et al, 2002; Murakami et al, 2002; Nakayashiki, 1990; O'Neal Page & Remington, 1967). Other organic compounds reported in eccrine sweat include glucose, pyruvic and lactic acid, urea, uric acid, creatinine, creatine, and ammonia (Bleay, Croxton, & de Puit, 2018).…”

The substances deposited from the fingertip onto a surface during contact between them represent a highly complex range of chemicals that can be exploited in a variety of ways in a forensic investigation. An overview is given of the multitude of chemicals that have been detected in fingermarks, including those occurring in endogenous sweat, metabolites of ingested substances, and exogenous substances picked up on the fingertip. Changes in chemistry that may occur between deposition of the fingermark and its subsequent forensic analysis are discussed, with particular reference to the ways in which these changes have been considered as a means of dating fingermarks. The ways in which fingermark enhancement reagents utilize the different chemicals present to reveal ridge is reviewed, together with how different classes of chemical can be sequentially targeted to optimize the number of fingermarks recovered.A field of increasing interest is the use of advanced analytical techniques incorporating mass spectrometry and imaging capability to simultaneously obtain additional contextual information about the donor of the mark while visualizing the fingermark ridge pattern. Examples are given of how such information can be applied in forensic investigations. It is concluded that an extensive "tool kit" of fingermark enhancement processes is already available to utilize the different chemicals present, and the advances that can be made in this field using conventional approaches are limited. There is, instead, significant potential to utilize analytical techniques to forensically exploit the chemical information within fingermarks but there are also significant barriers to their implementation in this way.

“…The presence of amino acids in human sweat has been widely reported in the biomedical literature (eg. [4][5][6][22][23][24][25]), with a wide range of amino acids being identified in human sweat (Table 3) [6]. It is known that the exact profile of amino acids present, and at what concentration, will depend upon the individual and a variety of other factors including general health, diet, gender and age [12].…”

The introduction of ninhydrin treatment as a chemical technique for the visualisation of latent fingermarks on porous surfaces revolutionised approaches to forensic fingermark examination. Since then, a range of amino acid sensitive reagents has been developed and such compounds are in widespread use by law enforcement agencies worldwide. This paper reviews the development and use of these reagents for the detection of latent fingermarks on porous surfaces. A brief overview is provided, including an historical background, forensic significance, and a general approach to the development of latent fingermarks on porous surfaces. This is followed by a discussion of specific amino acid sensitive treatments.

“…Among these 141 metabolites under study, the researchers discovered 24 metabolites that were connected to CHD [22]. A subset of these 24 discriminative metabolites, including the amino acids methionine, glutamine and histidine, has been found in human eccrine sweat [30]. Twenty-four metabolites were significantly and independently associated with incident CHD.…”

AI-empowered sweat metabolite analysis is an emerging and open research area with great potential to add a third category to biometrics: chemical. Current biometrics use two types of information to identify humans: physical (e.g., face, eyes) and behavioral (i.e., gait, typing). Sweat offers a promising solution for enriching human identity with more discerning characteristics to overcome the limitations of current technologies (e.g., demographic differential and vulnerability to spoof attacks). The analysis of a biometric trait’s chemical properties holds potential for providing a meticulous perspective on an individual. This not only changes the taxonomy for biometrics, but also lays a foundation for more accurate and secure next-generation biometric systems. This paper discusses existing evidence about the potential held by sweat components in representing the identity of a person. We also highlight emerging methodologies and applications pertaining to sweat analysis and guide the scientific community towards transformative future research directions to design AI-empowered systems of the next generation.
