Fluorescent polyelectrolyte for the visualization of fingermarks

Author affiliations

Abstract

A fluorescent polyelectrolyte, poly(allylamine hydrochloride) (PAH) functionalised with the 7-amino-quinolinium chromophore, has been synthesized for the visualization of latent fingerprints. Exposing fingerprints to pH neutral, dilute aqueous solutions of this polymer results in bright green fluorescent images, which are clearly visible to the naked eye.
