Novel design and approach to latent fingerprint detection on paper using a 1,2-indanedione-based bi-functional reagent

A novel 1,2-indanedione-based bi-functional reagent was designed for the development of latent fingerprints on paper substrates. The reagent was synthesized using a concise five-step protocol and applied using a modified multi-metal deposition (MMD) process. Positive images of latent fingerprints were developed showing preferential binding to the fingerprint ridges. Fingerprints that contain both amino acids as well as oily substances were successfully detected supporting the reagent’s efficiency.
