Amido Black (Naphthol Blue-Black) is a dye that is highly sensitive to the protein compounds found in blood. Previously only offered in powder form, this new solution simplifies the use of this reagent at crime scenes and is the perfect choice when attempting to recover weak or practically invisible shoeprint or latent fingerprint impressions. Amido Black may be used on porous and non-porous surfaces. The reaction product is a strong blue/black color, and it is best suited for use on light-colored surfaces permitting good visual contrast. Amido Black Solution is now supplied in a pump spray eliminating any advance preparation prior to use at the crime scene. When stored at room temperatures, the solution offers a shelf-life of up to one year. While Amido Black is non-flammable, it is corrosive and will stain many surfaces.
