“…Fingertips of a guitar player are rough with calluses due to plucking and brushing the strings, whereas that of a person who deals with a lot of paper work are often smooth [7]. Various physical traits of an individual can be determined by analysing the components of sebum and sweat present in the fingermarks, as the gland secretions are controlled by the body's hormone system Muramoto et al [8] demonstrated a novel test sample for the spatially resolved quantification of illicit drugs on the surface of a fingerprint using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) and Desorption Electrospray Ionization Mass Spectrometry (DESI-MS). Using an ink-jet-printed array of known quantities of drugs, researchers calibrated their mass spectrometry techniques to measure specks of the chemicals.…”

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.

A novel method for hierarchical screening of illegal adulterants in Fur seal ginseng pills products was developed by multi-dimensional fingerprint profiling analysis. Fingerprint feature of the samples was acquired by high-performance liquid chromatography analysis of 11 batches of samples with diode array detector and fluorescence detector, and then potential illegal adulterants including phosphodiesterase type-5 inhibitors, androgens, α receptor antagonists and yohimbine, were further separated at multiple wavelengths to reduce or remove interferences from sample matrix for highlight their chromatographic characteristics. Accordingly, a hierarchical screening strategy was designed by first-order and second-order fingerprints combined with spectral examination to achieve high accuracy and reliability. The method was successfully applied to screening of illegal adulterants in real samples, and it also exhibited good quantification performance through validation tests. From 16 batches of samples, three suspected samples were confirmed to be positive, containing 9.37μg/g of testosterone, 18.8 μg/g of tadalafil, and 48.5 μg/g of sildenafil, respectively. The recoveries and relative standard deviations were in the range of 83.6-103.1% and 4.2-6.8%, respectively. The proposed method provided a simple, efficient and promising alternative to monitoring functional foods.

“…Fingerprints are the prints left by the fingers or palms after touching a surface, which have been used as important physical evidence and cornerstone in the crime science to identify individuals. [1][2][3] In most cases, however, fingerprints are invisible to naked eyes because of their poor optical contrast, known as latent fingerprints (LFPs). Therefore, there has been intense interest in developing enhanced imaging methods to achieve clear visualization of LFPs.…”

Latent fingerprints (LFPs) imaging is the most important approach to identify individuals, and there is a persisting need for the development of simple, rapid, accurate, and universal LFPs recognition methods. The nitrogen‐ and sulfur‐doped solid fluorescent carbon dots (N,S‐SFCD) are synthesized with a simple microwave‐assisted method by using l‐glutathione and citric acid as precursors. The obtained N,S‐SFCD has a uniform size from 2 to 7 nm with quantum yield over 48%. The presence of heteroatoms and functional groups on the surface endows the N,S‐SFCD with good dispersibility and strong fluorescence emission, and overcomes the typical aggregation‐induced fluorescence quenching, thus allowing the N,S‐SFCD to be used in both solution and their powder forms. Furthermore, the color‐tunable fluorescence, electrostatic interaction with fingerprints, and good stability enable N, S‐SFCD to act as an excellent chemosensor for fluorescence imaging. LFPs are detected with high resolution through powder method, and their second‐ and third‐level substructures are clearly identified. The method is validated for LFPs visualization on various substrates, and aged (7, 15, and 30 d) LFPs can also be successfully stained with N,S‐SFCD. The results demonstrate that the N,S‐SFCD as a developer has great potential in LFPs imaging for forensic investigations.
