Fluorescent Polymer Detects Crime Scene Fingerprints

• technewsdaily.com
 A significant portion of crime scene investigation involves searching for what are called "latent fingerprints," or deposits of secreted sweat and natural oils transmitted by touch onto a flat surface, and usually invisible to the naked eye.

The ridges on human fingertips, also called epidermal ridges or friction ridges, make the lines, whorls and swirls in these latent fingerprints. These patterns are virtually unique to each individual person (the chances of two people having the same prints are 64 billion to one), which makes fingerprints an excellent way to identify who was present at a crime scene.
