Abstract
Natural yellow 3 (curcumin) is a naturally occurring dye that is used as a food coloring. In this technical note, the authors show that natural yellow 3 can be incorporated into a formulation closely equivalent to that used for the blue-black fat stain solvent black 3. When this formulation is applied to surfaces, fingermarks contaminated with many types of greasy contaminant materials and sebaceous sweat become strongly fluorescent. This has potential for use on dark surfaces where greasy marks enhanced with the solvent black 3 reagent would not be readily visible. (Published Abstract)
