D.F.O. reacts to the amino acids present in a latent fingerprint. The resulting prints will fluoresce with the use of a forensic light source. WebDFO was first suggested as a latent fingermark development reagent by Pounds in 1990 [], and since then, modifications to the original DFO method have been investigated by various research groups in an attempt to stabilise the working solution and improve the fingermark ridge contrast produced by the technique.Masters et al.[] investigated the usage of DFO …
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. WebJun 10, 2013 · Results showed that use of ethanol as a solvent to assistant solubility exerts a substantial influence on the sensitivity of the reagent. The optimum ratio of DFO solution with PVP, in ethanol solution, was 1:10 (v/v) and the best concentration of PVP in the ethanol solution was found to be around 5% (Table 1).
