Question: 1 / 400

Which reagent is typically used for fluorescence detection of latent prints?

Ninhydrin

Coomassie Blue

Amino Black

DFO

DFO, or 1,8-diazafluoren-9-one, is a reagent commonly used for the fluorescence detection of latent prints, particularly those made from perspiration containing amino acids. When latent prints are treated with DFO, it reacts with specific amino acids and fluoresces under ultraviolet (UV) light. This property makes DFO highly effective for visualizing and documenting latent fingerprints on various surfaces.

The fluorescence emitted by DFO allows examiners to obtain a clear image of the fingerprint pattern, which can enhance the identification process. This makes DFO a valuable tool in forensic science, especially when the prints are weak or not easily visible with other methods.
