DFO 是一种用于使在多孔表面上，能够发现指纹的化学物质。

DFO (9H-1,8-Diazafluoren-9-one) is used to find fingerprints on porous surfaces.

1,8-diazafluoren-9-one (DFO) is used in the forensic field to enhance latent fingerprints deposited on porous surfaces due to the formation of fluorescent products by reacting with the amino acids present in the papillary exudate. DFO has been the most used because of its excellent enhancing properties.
