1,2-Indanedione — A winning ticket for developing fingermarks: A validation study

In 1997, Joulli é and co-workers first studied 1,2-indanedione as a potential ninhydrin-analogue for the visualization of latent fingermarks [1,2]. The new reagent reacted with amino acids to produce a fluorescent, pink-colored product, which was later named Joullié’s pink [3]. The significant advantage over ni nhydrin was its ability to fluoresce with no further treatment. Studies by various research groups have shown that 1,2-indanedione, as a fingerprint reagent, can potentially exceed both ninhydrin and DFO [4,5].
