ANS (8-anilinonaphthalene-1-sulfonate) has shown itself to be a valuable and sensitive reagent method for the detection of latent and greasy prints on porous surfaces. The working solution is sprayed onto the porous surface where latent or greasy prints are suspected and the prints show bright yellow fluorescence against dark background under ultraviolet (UV) lamp (long wavelength) illumination. The advantages of this method are its rapid reaction, no heat needed, high sensitivity, no unpleasant odor, simplicity, and convenience in processing.
