To Be a Crime Scene Investigator
Ninhydrin is a chemical substance that reveals latent fingerprints on porous
surfaces, such as paper, cardboard, and raw wood, by reacting with amino acids
in the fingerprints. It reacts in ten to twenty minutes, developing a purplish image
that ...

Sequencing of proteins and peptides
A suitable amount of peptide for detection with ninhydrin is about 5 nmol-cm-2,
equivalent to 1-2 nmol on thin-layer peptide maps or 10-20 nmol on peptide
maps on paper, depending on the sizes of the spots. Three recipes are given
below.

Sensitivity is 0.5 nmol. 5. Ninhydrin (1.0 g) in absolute ethanol (700 mL), 2,4,6-
collidine (29 mL), and acetic acid (210 mL) has been used for spraying on
solvent-free cellulose layers (40). The chromatogram is then dried for 20 min at
90°C. 6.

Laser Techniques in Luminescence Spectroscopy
Since the 1960s, ninhydrin has been the workhorse of latent fingerprint detection
on porous surfaces (mainly paper). In the 1970s, Morris and co-workers
investigated the complexation of RP with metal salts (for example, Nickel (Ni),
Zinc (Zn)), ...
Tuan Vo-Dinh, D. Eastwood, 1990
The test is conducted with a solution of about 0.5 percent ninhydrin in some
appropriate solvent (such as ethanol or acetone). A number of different
formulations are commercially available under names such as Arklone and
Fluorisol.
