Abstract

The ninhydrin/zinc chloride method for laser latent fingerprint development is not well suited to the use of frequency-doubled neodymium:yttrium aluminum garnet (Nd:YAG) lasers. We have examined several ninhydrin analogues and find that benzo(f)ninhydrin is very well matched to the use of this laser.
