“…Although reviews of fingerprint research are of high quality and very detailed, they reveal a general lack of degradation product analyses in studies of fingerprint aging [39,[41][42][43]. But Mountfort et al should be named as they identified mono hydroperoxides as degradation products of squalene in solution and in fingerprints [31].…”

Abstract. GC-MS investigations were carried out to elucidate the aging behavior of unsaturated fatty acids in fingerprint residues and to identify their degradation products in aged samples. For this purpose, a new sample preparation technique for fingerprint residues was developed that allows producing N-methyl-N-trimethylsilyltrifluoroacetamide (MSTFA) derivatives of the analyzed unsaturated fatty acids and their degradation products. MSTFA derivatization catalyzed by iodotrimethylsilane enables the reliable identification of aldehydes and oxoacids as characteristic MSTFA derivatives in GCMS. The obtained results elucidate the degradation pathway of unsaturated fatty acids. Our study of aged fingerprint residues reveals that decanal is the main degradation product of the observed unsaturated fatty acids. Furthermore, oxoacids with different chain lengths are detected as specific degradation products of the unsaturated fatty acids. The detection of the degradation products and their chain length is a simple and effective method to determine the double bond position in unsaturated compounds. We can show that the hexadecenoic and octadecenoic acids found in fingerprint residues are not the pervasive fatty acids Δ9-hexadecenoic (palmitoleic acid) and Δ9-octadecenoic (oleic acid) acid but Δ6-hexadecenoic acid (sapienic acid) and Δ8-octadecenoic acid. The present study focuses on the structure identification of human sebum-specific unsaturated fatty acids in fingerprint residues based on the identification of their degradation products. These results are discussed for further investigations and method developments for age determination of fingerprints, which is still a tremendous challenge because of several factors affecting the aging behavior of individual compounds in fingerprints.

“…However, recent advances by our research group using an immuno-labelling approach based on the use of fluorescently labelled, antibody-functionalised magnetic particles have shown the detection of drug metabolites endogenously produced in the latent fingermarks of drug users [18][19][20]. In addition, Rowell et al were able to show isolated patches of cocaine contamination in a fingerprint obtained from an individual being treated at a drug addiction centre using surface assisted laser desorption/ionisation time-of-flight mass spectrometry (SALDI-TOF-MS).…”

A sensitive and versatile competitive enzyme immunoassay (cEIA) has been developed for the quantitative detection of cocaine in complex forensic samples. Polyclonal anti-cocaine antibody was purified from serum and deposited onto microtiter plates. The concentration of the cocaine antibody adsorbed onto the plates, and the dilution of the cocaine-HRP hapten were both studied to achieve an optimised immunoassay. The method was successfully used to quantify cocaine in extracts taken from both paper currency and latent fingermarks. presents a simple and cost-effective alternative to the current mass spectrometry based techniques for the quantitation of cocaine at forensically significant concentrations.

“…The composition of fingerprints already deposited on surface can change with time due to a variety of factors, such as evaporation of volatile components of fingerprints, diffusion of fingerprints into porous surface, exposure to light, temperature and humidity, and many more [1,5]. Even though there are a number of optical, chemical and physical techniques available for fingerprint analysis a considerable portion of the latent fingerprints still escape detection, resulting in inaccurate analysis.…”

“…Owing to the fact that this pattern is unique to each individual and doesn't change throughout a person's life, it has been used as a biometric identifier by the criminologists and law enforcement officers in forensic investigations since late 19th century [1]. Apart from the scars which originated from any accidents, fingerprints remain same throughout a person's life.…”

For deciphering the secrets of forensic science, nanotechnology has quite extensively been utilized. Generally, for identifying the fingerprints, a lot of combination of different materials and film assemblies have already been utilized. Since the mode of interaction between the nanoparticles and fingerprint marks, is still not clearly understood, fabricating the nanoparticle assemblies for their identification is quite challenging. Complete identification of fingerprint marks which are generally because of a combination of some kind of proteins and fatty acids, is still a difficult task and is only partially being done with the help of different techniques. Nanotechnology has already shown immense potential in many fields like medicine, molecular biology, genetics, material science etc. and it has also marked promising potential even in forensic analysis studies. This review aims to discuss the details of the process of fingerprint formation, their role in forensic analysis along with the latest advances in the field of nanotechnology for their identification. This information may enhance our understanding about the progress in the forensic analysis of fingerprints, which may further be utilized in solving the puzzle of various criminal cases.
