The most common reagents for fingerprint development on porous surfaces are ninhydrin and DFO. However, a large number of different reagent formulations are in use in fingerprint laboratories around the world. 1,2-Indanedione ...

The chemical 5-methylthioninhydrin was developed in the early 1990s for treating fingermarks on porous surfaces. Although many researchers showed the promise of this chemical during the years between 1990 and 1997, current ...

Multimetal deposition (MMD) has not found routine application because of its complexity and inconsistent results. Recent research that sought to overcome these problems resulted in the development of a new formulation ...

A previously identified difficulty with the development of latent fingerprints on low-density polyethylene (LDPE) by vacuum metal deposition (VMD) is that excess gold deposition prevents effective zinc deposition and so ...
