Product Overview

DFO (1,8-Diazafluoren-9-one) is an advanced Ninhydrin analogue specifically designed to enhance latent fingerprints on porous surfaces, especially paper-based evidence. Like Ninhydrin, DFO reacts with amino acids present in fingerprint residues, but offers significantly greater sensitivity and fluorescent visualization, making it a powerful tool for forensic professionals aiming for maximum print recovery.

When exposed to appropriate light sources—typically in the 510–560nm range—DFO-treated prints exhibit strong fluorescence, allowing for superior photographic documentation and pattern analysis. It is particularly effective in processing aged or faint prints that may not develop well with standard reagents.

Scientific research has shown that DFO can reveal up to 2.5 times more latent prints than using Ninhydrin alone, making it a preferred choice for high-volume document examination and cold case reviews where evidence preservation is critical.

Key Features:

• Reacts with amino acids to develop latent fingerprints on paper and other porous materials
• Fluorescent analogue of Ninhydrin, providing enhanced sensitivity
• Reveals up to 2.5 times more prints compared to Ninhydrin-only development
• Produces strong fluorescence under green light (510–560nm) for easy visualization
• Ideal for document evidence, cold cases, and aged materials
• Supports high-resolution photographic documentation and court-ready analysis

With DFO, forensic experts gain a cutting-edge solution for latent print recovery on paper-based evidence—delivering both sensitivity and reliability in even the most demanding investigative scenarios.
