DFO (Cat No.:I020482) is a fluorescent dye employed in forensic science to improve the visibility of latent fingerprints left on porous surfaces. It works by reacting with amino acids found in nipple exudates, which are naturally present in sweat. When DFO is applied to the surface containing latent fingerprints, it forms a stable and fluorescent complex with the amino acids, enhancing the contrast and making the fingerprints more easily detectable under appropriate lighting conditions. This technique aids in fingerprint identification and can be valuable in criminal investigations.
