Resumen de Fast, Easy, Reproducible Method for Planting Fingerprints for Ninhydrin, Iodine Development
Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where the chemistry of fingerprint staining is to be discussed. The current work was completed in the context of a university, nonmajors’ chemistry laboratory but can be broadly applicable for other university classes, high school classes, or public demonstrations.
