Chemistry of extracting high-contrast invisible fingerprints from transparent and colored substrates using a novel phosphorescent label

Abstract: Conventional fluorescent powders for developing latent fingerprints show characteristics of complicated operation, auto-fluorescence interference and high toxicity. To overcome these issues, we report a facile methodology to extract high contrast fingerprints on non-porous and porous substrates using a phosphorescent label.

“…Public security remains a global challenge and the utilization of LFs, bar‐codes for anti‐counterfeiting, and confidential data encryption, among others, are being currently applied by forensic institutions . In particular, LFs appears to be the best option for personnel identification in forensic investigations due to their high stability, uniqueness and complexity of ridges patterns .…”

“…Fluorescent-labeledmaterials (FLMs) are very important entities with widespread applicability, ranging from white light emitting diodes (WLED), [1] molecular imaging, [2] in vivo and in vitro cellular targeting and imaging, [3] to detection of latent fingerprints (LFs) in the forensic sector. [4][5][6][7][8][9] Within this context, FLMs possess better featurest han classical fluorescent organic dyes, [3,10] including highera bsorption coefficientsa nd sensitivity,a voiding possible photobleaching, larger emission lifetimes and very low toxicitya llowing them to be applied in vitro and in vivo analysis. [11] Public security remains ag lobal challenge and the utilization of LFs, bar-codesf or anti-counterfeiting, and confidential data encryption, among others, are being currently appliedb yf orensic institutions.…”

“…In every case investigation and accused identification in the illegal activity, these fingermarks play a critical role. [1][2][3] The majority of the time, fingermarks at crime scenes are not visible to the naked eye. In order to see such invisible fingermarks, a physical or chemical technique is needed, which is more commonly known as latent.…”

“…By contrast, latent fingerprints (LFPs) are the most significant method to recognize individuals for identification and needed for the development of accurate, simple, and rapid LFPs identification methods. There have been numerous reports on the use of CDs as fluorescent agents, which have shown excellent performance for cell leveling and fingerprint development. The CDs which possess the properties like (i) no autofluorescence background, (ii) no quenched by their aggregation in the solid-state, (iii) high fluorescent efficiency, and (iv) dispersion mediums, etc. are considered as a suitable contender for cell leveling and LFPs.…”
