A tetraphenylethene-based dye for latent fingerprint analysis

Abstract A tetraphenylethene-based dye (FLA-1) was used to develop for enhancing the visualization of the latent fingerprints on the surfaces of various substrates. The resolution of the fingerprints visualized by the probe FLA-1 is enough to offer a positive match according to the information supplied from a police database. Experimental results confirm the accuracy of using the probe for LFPs detection.
