1,8-Diazafluoren-9-one (DFO) is an aromatic ketone first synthesized in 1950. It is used to find fingerprints on porous surfaces. It makes fingerprints glow when they are lit by blue-green light. DFO reacts with amino acids present in the fingerprint to form highly fluorescent derivatives. Excitation with light at ~470 nm results in emission at ~570 nm. WebDFO (1,8-diafluoren-9-one) is an analog of ninhydrin that reacts with amino acids, and is an effective reagent for developing latent fingerprints on porous surfaces. Due to its …
WebWhen these two fingerprint reagents are used consecutively, more fingerprints are able to be identified. Because Oil Red O (ORO) targets lipids, the strategy is to add this reagent … Web3) On an average, DFO reagent develops 3 times more fingerprints than ninhydrin. 4) If DFO reagent fails to detect a latent impression, ninhydrin method can still be tried out on the same surface. However, if ninhydrin reagent does not develop a particular imprint, DFO method cannot be extended for its detection 20.
