In order to address the need for consistency and generality in chemical methods developed for detecting latent fingerprints on paper substrates, this project developed a protocol using 1,2-indanedione-based bi-functional reagents.

Abstract

A series of novel bi-functional reagents were designed and synthesized using a concise, five-step sequence. An optimized development condition that is tailored to the type of paper substrate that requires processing was discovered, allowing potential application in practical criminal work where evidence processing is an irreversible process. The study also determined the underlying mechanism of interaction between the bi-functional reagent and fingerprint residue. (Publisher abstract modified)
