| In vitro study | 1,2-indanedione (1,2-IND) and 1,8-diazafluoren-9-one (DFO) are 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, even if it is more expensive and relatively toxic in comparison with the 1,2-IND. |

54078-29-4 - Introduction
DFO belongs to amino acid and polypeptide fluorescence analysis reagent. DFO reacts with α-amino acid to produce a red product with strong fluorescence. In recent years, new applications have been obtained in sweat fingerprint display identification, and the detection sensitivity is far better than the existing sweat fingerprint testing reagents.
