Dfo reagent
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 fluorochrome properties, DFO has the additional ability when used with the proper alternate light and filter, to fluoresce and enable the exami
