The current research focuses on identifying chemical reagents that can be used to detect latent fingerprints on stainless steels in submerged aquatic environment which can damage the quality of the fingerprints. Fingerprint data has been collected from the limited environment and we used a scoring system to identify chemical reagents that can preserve the quality of the fingerprints as well as prolong the detection period. As a result, we used a collection of chemical reagents that can be used on wet surface and found the detection rate is significantly diminished after 3 days of water exposure. However, within 3 days of exposure we were still able to identify the fingerprints with the reagents. Interestingly, SPR and Errosoferric Oxide, which are commonly used on wet surface, was not effective in our study and the reagent CA that is normally used on non-porous surface also was not effective and had the lowest detection score. Nile Red and ORO regents however had outstanding detection scores in comparison with other reagents. This research can be further used to identify latent fingerprints on stainless steels in aquatic seawater.
