1,8-Diazafluoren-9-one (DFO) is an
aromatic ketone
In organic chemistry, a ketone is a functional group with the structure R–C(=O)–R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group –C(=O)– (which contains a carbon-oxygen double bo ...
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.
