How do forensic scientists find fingerprints? (with Nicki Stewart)

About this episode

This episode explores the various methods forensic scientists use to reveal fingerprints beyond traditional black powder techniques.

There are a lot more ways to reveal a fingerprint than the black powder you see on TV. In this second part of our forensic chemistry series with Nicki Stewart, we explore the surprising chemistry behind fingerprints. From powders and iodine vapor to super glue fumes and chemical reactions, we break down how forensic scientists reveal invisible fingerprints—and why choosing the right method depends entirely on the surface, the chemistry, and the evidence they’re trying to preserve.
