Highly efficient latent fingerprint detection by eight-dansyl-functionalized octasilsesquioxane nanohybrids

The largely demand in continued security issues makes necessary the development of novel materials with outstanding properties to improve the current detection techniques. In this context, latent fingerprint (LF) by fluorescent labeled materials (FLM) is one of the most attractive personnel identification methodologies. Here, two FLM based on polyhedral oligomeric silsesquioxane (POSS) nanohybrids labeled with dansyl chromophores have been synthesized and fully characterized. Their photophysical properties have confirmed that these materials clearly possess the prime qualifications as suitable LF sensing platforms. In fact, they adequately detect LFs on glassy surface with excellence legibility.Alexander von Humboldt FoundationGeneralitat ValencianaUniversit¨at RegensburgMinisterio de Ciencia, Innovación y Universidade
