A fluorescent molecular rotor for the in situ imaging of latent fingerprints

RSC Adv. 2022 Nov 22;12(51):33180-33186. doi: 10.1039/d2ra06728e. eCollection 2022 Nov 15.


Efficient techniques for developing latent fingerprints are invaluable resources to solve crimes. In this work, we developed a fluorescent molecular rotor probe that responds to hydrophobic and viscous environments and visualizes latent fingerprints with level 3 details. We believe that the simple and convenient features of LFP-1 will benefit forensic practice.
