Intentionally exposing living skin to cyanoacrylate fumes is NOT covered in the material safety data sheets (MSDS) of any cyanoacrylate products I have ever seen.

I recommend against using any latent print chemical development procedures on living persons.

Here is a link on the topic of prints on skin.

Need advice on safest/most reliable method of latent print (made from human sweat) retrieval from living skin tissue. My son would like to build and use--with adult supervision--a superglue chamber.(have found instructions.) Can this be used on living human tissue? Also, he wants to test temperature by using different surface temperatures of skin, and humidity by adding or subtracting a water dish in the chamber.This is a brand new topic for our family. Any advice, comments, thoughts or control ideas are greatly appreciated!!
