According to forensic science recommendations, are carbon dots capable of reliably developing latent fingerprints?

Carbon dots (CDs) are zero-dimensional carbon nanomaterials that have been subject of considerable interest due to their remarkable electronic and optical characteristics. Their adjustable properties have gathered attention in different fields, including biological sensing, drug delivery, photodynamic therapy, photocatalysis, solar cells, and latent fingerprint development. In forensic science, the frequently reported outstanding photoluminescence behavior and biocompatibility of CDs are particularly important.

Comparison of practical techniques to develop latent fingermarks on fired and unfired cartridge cases.

We have tested some widely used and practical fingermark enhancement techniques such as powdering (regular powder dusting and magnetic powder application), cyanoacrylate fuming, fluorescent dying (basic yellow 40), gun blueing solutions and acidified hydrogen peroxide solutions. The results were evaluated and compared in order to establish best procedures on processing cartridge cases. The tests were performed on brass discs subjected to three different temperatures (room temperature, 63 and 200°C), and on fired and unfired cartridge cases.
